Przedstawiono sposób syntezy oraz właściwości powłok na bazie surowca odnawialnego (kwasu rycynolowego pozyskiwanego z oleju rycynowego) z dodatkiem kwasu benzoesowego i żywicy epoksydowej. Ze względu na dużą lepkość takiego oligoestrolu prowadzono modyfikację za pomocą oligowęglanodiolu i oligoeterodiolu. Przygotowano także powłoki, w których jako składnik izocyjanianowy stosowano dodatek izocyjanianów cyklicznych, trimeru izoforonodiizocyjanianu (tIPDI) i trimeru heksametylenodiizocyjanianu (tHDI), do polimerycznego 4,4’ diizocyjanian difenylometylenu (pMDI). W celu zapewnienia właściwości antykorozyjnych dodawano dodatki nieorganiczne, nanomagnetyt oraz fosforan(V) cynku(II)

In this study, physical and functional properties of the cement composites containing ZnO, ZnO/lignin and lignin admixtures were investigated using Response Surface Methodology (RSM). The I-optimal design based on RSM was used to assess the influence of ZnO-based doping agent, of either commercial or synthetic origin, on cement composite production in the function of average compressive strength and cost. Polynomial mathematical models were developed by RSM confronting results from the experimental design. The accuracy and precision of the utilized models established by I-optimal design were tested using Analysis of Variance (ANOVA). The first stage of formulation optimization revealed that the use of commercially available ZnO-based admixture no. 4 (ZnO-SA, supplied by Sigma Aldrich) allowed to achieve the desired results, passing all the requirements, i.e., the best microbial purity combined with reasonable cost, followed by satisfactory physical properties. In the second stage of formulation optimization, the influence of implementing the hybrid materials, i.e., ZnO-SA mixed in different proportions with lignin was evaluated. RSM revealed that doping admixture no. 3, i.e., ZnO-SA/lignin (5:1), is the best candidate, which comprised augmented functional and physical properties of the fabricated cement composite. This component exhibited the best microbial purity as well as the lowest total pore volume, followed by satisfactory physical properties. Verification of the model findings indicated considerable agreement between the predicted and experimental values. From the findings, it was confirmed that a reasonable cost-performance balance for cement composites can be achieved using ZnO-SA and ZnO-SA/lignin (5:1).

In this study, the electrospray deposition (ESD) method was used to deposit carbon nanotubes (CNT) onto the surfaces of carbon fibers (CF) in order to produce hybrid carbon fiber-carbon nanotubes (CF-CNT) which is rarely reported in the past. Extreme high-resolution field emission scanning electron microscopy (XHR-FESEM), high-resolution transmission electron microscopy (HRTEM) and x-ray photoelectron spectroscopy (XPS) were used to analyse the hybrid carbon fiber-carbon nanotube (CF-CNT). The results demonstrated that CNT was successfully and homogenously distributed on the CF surface. Hybrid CF-CNT was then prepared and compared with CF without CNT deposition in terms of their tensile properties. Statistically, the tensile strength and the tensile modulus of the hybrid CF-CNT were increased by up to 3% and 25%, respectively, as compared to the CF without CNT deposition. The results indicated that the ESD method did not cause any reduction of tensile properties of hybrid CF-CNT. Based on this finding, it can be prominently identified some new and significant information of interest to researchers and industrialists working on CF based products.

The potential for expanding the variety of catalytic methods for carbon-carbon bond formation is being currently explored in many research centres all over the world. An increasing use of selected d-block metals as catalysts in the synthesis has brought new methods of functionalization of organic and organometallic compounds of great importance for development of polymer chemistry and organic chemical technology [5, 6]. This work describes very precise and controlled catalytic transformations as useful tools for the synthesis of new E-conjugated organic, organosilicon molecular and polymeric compounds. The combination of Suzuki-Miyaura coupling and silylative coupling reactions as a simple and efficient method is established for designing new E-stereoregular hybrid materials in the presence of well-defined transition metal (TM) catalysts. All presented compounds can be interesting precursors for a further functionalization that may significantly increase the possibility of their application in the design and synthesis of new functional materials.

Organosilicon compounds are of great significance in modem world and may be found in various branches of chemistry and our daily life. The silsesquioxanes are their specific derivatives. Their uniqueness results from the presence of inorganic siloxane Si-O-Si core and tunable functional organic coronae which classifies them as hybrid systems. These compounds attract great attention due to their exclusive properties derived from chemically and thermally robust organic- inorganic framework, e.g. thermal stability, high oxidation resistance, good mechanical and optical characteristics, and other features. This fact, along with the elaboration of synthetic routes for their functionalization, affects the broad area of their application. Many research laboratories are focused on development of selective and effective synthetic procedures for obtaining of the abovementioned compounds. In recent years, the number of reports on the synthesis of hybrid materials with variety of applications has been growing rapidly, however, it still meets unknown perspectives.

Polymers of natural origin have been gaining increasing significance in sciences, as well as the industry. Owing to their renewable nature, unique properties and wide availability, they are components that can be used for numerous advanced applications. Lignin, a biopolymer, which is a waste product separated from the widely understood biomass, most usually generated in the pulp and paper industry, falls in line with this trend. In this context, the importance of cellulose, which is used in the production of paper and by-products is greater. Whereas lignin, in the vast majority, i.e. approx. 95-98%, constitutes an energy source generated as a result of its combustion. However, nowadays, due to the huge potential arising from the specific structure of lignin and its properties, attempts are being made at using this material in many different applications within the so-called high added value. Lignin, as a commonly used polymer of unique chemical structure and properties, has recently become a source of many studies utilizing its potential in the preparation of functional materials and/or biomaterials, including hybrid ones. Such systems consist of appropriate inorganic and organic elements, which as a whole constitute a functional product with special properties, not exhibited by individual components. This provides unlimited possibilities in terms of engineering, shaping and practical application in newly developed systems. The huge interest in hybrid materials and/or biomaterials results from their potential applications, namely, in medicine, electronics, optics, electrochemistry, energy storage etc. Therefore, it nowadays becomes justified and important to try and develop new, functional systems, which owing to their specific properties could result in interesting application-wise possibilities in everyday life. Therefore, the attempt to use lignin as a source of many attractive and prospective possibilities is not without significance.

Badania prezentowane w artykule miały na celu określenie wpływu polimerów rozpuszczalnych w wodzie na właściwości gipsu. Zestalanie gipsu obejmuje uwodnienie i krystalizację oraz utworzenie filmu polimerowego w porach materiału. Te procesy są badane różnymi metodami, takimi jak pomiary zestalania, właściwości mechaniczne, mikroskopia elektronowa, różnicowa kalorymetria skaningowa i inne. Dodatki polimerowe działają przede wszystkim jako opóźniacze procesu zestalania gipsu, powodując zmianę właściwości mechanicznych w wyniku modyfikacji jego struktury morfologicznej. Mechanizm wzrostu kryształów gipsu podczas uwodnienia półwodnego siarczanu wapnia jest procesem kontrolowanym przez nukleację (równania Avramiego).

The study presented in this article is focused on the influence of water soluble polymers on gypsum properties. Gypsum setting involves: gypsum hydration – crystallization and formation of polymer film in material pores. The processes are studied by various methods such as setting and mechanical measurements, scanning electron microscopy, differential scanning calorimetry and others. Polymer additives act first of all as a retarder of setting and change mechanical properties of material due to modification of its morphological structure. The mechanism of gypsum crystal grow during hydration of chemihydrate calcium sulfate was predicted to be nucleation control process (Avrami equation was applied).

In the framework of this study, Al2O3-lignin hybrid materials differing in terms of the weight ratio of the inorganic and organic components were designed and obtained. The method of mechanical grinding of ingredients with simultaneous mixing using a mortar grinder and a high-performance ball mill was used in order to obtain the above-mentioned systems. The effectiveness of obtaining alumina- lignin materials was confirmed using Fourier transform infrared spectroscopy (FTIR) and, indirectly, by the colorimetric analysis. FTIR analysis allowed to confirm that hydrogen bonds formed between the components and classify the resulting systems as Ist class hybrid materials. In the course of the conducted research, the relatively high thermal stability of the hybrid materials was also confirmed and the dispersion and morphological character (SEM) of the obtained systems was determined. Favourable physicochemical and microstructural evaluation allowed to qualify the alumina-lignin hybrid systems as functional admixtures for cement mortars. As part of the tests, it was confirmed that the presence of lignin in the cement composites contributes to the increase of the plasticity of the mixture. In turn, the inorganic component allowed to preserve (and, in case of selected systems, improve) the mechanical properties of the final composites. The most favourable results of application tests were obtained for alumina-lignin hybrid systems with a weight ratios equal to 5:1 and 2:1. The analysis of these systems indicated that there is a clear improvement of mechanical properties, whit a simultaneous enhancement of the plasticity of the mixture in comparison to the reference sample.

The intercalation into interlayer spaces of montmorillonite (MMT), obtained from natural calcium bentonite, was investigated. Modification of MMT was performed by the poly(acrylic acid-co-maleic acid) sodium salt (co-MA/AA). Efficiency of modification of MMT by sodium salt co-MA/AA was assessed by the infrared spectroscopic methods (FTIR), X-ray diffraction method (XRD) and spectrophotometry UV-Vis. It was found, that MMT can be relatively simply modified with omitting the preliminary organofilisation – by introducing hydrogel chains of maleic acid-acrylic acid copolymer in a form of sodium salt into interlayer galleries. A successful intercalation by sodium salt of the above mentioned copolymer was confirmed by the powder X-ray diffraction (shifting the reflex (001) originated from the montmorillonite phase indicating an increase of interlayer distances) as well as by the infrared spectroscopy (occurring of vibrations characteristic for the introduced organic macromolecules). The performed modification causes an increase of the ion exchange ability which allows to assume that the developed hybrid composite: MMT-/maleic acid-acrylic acid copolymer (MMT-co- MA/AA) can find the application as a binding material in the moulding sands technology. In addition, modified montmorillonites indicate an increased ability for ion exchanges at higher temperatures (TG-DTG, UV-Vis). MMT modified by sodium salt of maleic acid-acrylic acid copolymer indicates a significant shifting of the loss of the ion exchange ability in the direction of the higher temperature range (500–700°C).

The aim of this study was to effectively combine synthetic magnesium silicate with the lignin-derived biopolymer calcium lignosulfonate, using the in situ sol-gel route. Magnesium ethoxide and tetraethoxysilane were used as precursors of MgO and SiO2. The synthesis was carried out in alcoholic solution with the addition of ammonia solution as a promoter of hydrolysis. Calcium lignosulfonate was introduced to the reaction medium prior to the synthesis of magnesium silicate. The resulting hybrid powder material was thoroughly characterized, including morphology and particle sizes (SEM microscopy and the DLS technique), porous structure parameters (the BET method and BJH model), thermal stability (TG analysis) and electrokinetic stability (LDV measurements). FTIR spectral analysis was carried out to confirm the effectiveness of the proposed synthesis methodology. Based on the results, a mechanism is proposed for the MgSiO3/lignosulfonate interactions. The resulting novel type of hybrid material combines the multifunctional nature of the biopolymer (diversity of functional groups) with the well-developed porous structure of synthetic magnesium silicate. Its physicochemical parameters were found to depend significantly on the quantity of lignosulfonate used in the synthesis.

Organic/inorganic hybrid materials consisting of quantum dots and conjugate polymers are important for the application in light emitting devices. In the present work, we have studied the effect of CdS and CdS/ZnO nanoparticle addition on the structure and fluorescence properties of spin coated PVK (poly(N-vinyl carbozole)) nanocomposite films. CdS nanoparticles were synthesized by simple co-precipitation technique and ZnO shell was grown on the CdS nanoparticles by simple wet chemical approach. The nanoparticles and the hybrid nanocomposites have been characterized by using XRD, SEM, FT-IR, optical absorption and fluorescence spectroscopic techniques. The absorption peak for pure PVK remains at 345.5 nm accompanied with minor hump ~480 nm resulting from the incorporation of nanoparticles. It has been observed that the addition of nanoparticles to the hybrid material results in the enhancement of fluorescence intensity at 410 nm to 450 nm spectral regions. These results are important for the development of new light emitting devices at low fabrication costs.

Artykuł stanowi przegląd literatury dotyczącej syntezy oraz charakterystyki materiałów polimerowych zawierających silseskwioksany (POSS). Przedstawiono metody otrzymywania hybrydowych materiałów polimerowych zudziałem funkcjonalizowanych POSS na drodze click chemistry, polikondensacji, poliaddycji, metatezy zotwarciem pierścienia ipolimeryzacji rodnikowej zarówno konwencjonalnej, jak i kontrolowanej (ATRP).

The paper is a literature review concerning the synthesis and characterization of polymeric materials containing silsesquioxanes (POSS). The methods of preparation of the functionalized POSS-containing hybrid polymeric materials using click chemistry, polycondensation, polyaddition, ring-opening metathesis and free-radical polymerization — both conventional and controlled (ATRP) — have been presented. Depending on the polyreaction mechanism, the type of monomer used and the structure of POSS cage, linear copolymers with silsesquioxane units in the main or side chains as well as star copolymers can be obtained. The incorporation of POSS into copolymer system results in increased glass transition and decomposition temperatures, better resistance to oxidation and improved mechanical properties when compared to the conventional polymeric systems.
