The first part of research is concentrated on the examination of four kinds of carbon nanomaterials: graphene oxide (GO), multi-walled carbon nanotubes (MWCNT), multi-walled carbon nanotubes functionalized by authors in acids mixture (MWCNT-F) and multi-walled carbon nanotubes with hydroxyl groups (MWCNT-OH). Their microstructure was observed in transmission electron microscopy (TEM). Based on these microphotographs, the diameters of carbon nanotubes were measured. Then, in order to determine the chemical composition of GO, MWCNT-F and MWCNT-OH, X-ray photoelectron spectroscopy was applied. The second part of study concerns the properties of the coatings deposited electrophoretically on titanium surface from previously examined nanomaterials. The coatings from individual nanomaterials, as well as hybrid layers (combination of two kinds of nanomaterial: graphene oxide with one of the nanotubes’ type) were deposited. Microstructure of the coatings was evaluated with the use of scanning electron microscopy (SEM). Furthermore, surface properties, important while considering usage of these materials in biological applications: wettability and surface free energy were evaluated. These materials are meant for application in regeneration and stimulation of nerve cells. All the research carried out so far indicate the influence of nanotubes’ functionalization degree on the properties of their suspension, as well as the characteristics of the deposited coating. It also influences the interaction between two types of nanomaterials. Functionalization in strong acids introduces functional groups which change nanotubes’ dimensions, properties and behavior in solution.
