The purpose of this study was to obtain polyamide 6 nanocomposites with different organically modified clays and to study the biotic degradation behaviour vs mechanical properties of the obtained materials. Thermal stability of pure organoclays was investigated using thermogravimetric analysis (TGA). The prepared nanocomposites were characterized by X-ray diffraction (XRD) and infrared spectroscopy (IR). The evolution of mechanical properties was also studied. The obtained results confirm good interactions of nanofillers with the polymer, showing the formation of intercalated and/or partially exfoliated structures. The nanocomposites showed higher thermal stability compared to pure polymer, and advantageous mechanical properties. Finally, a discussion related to the effects of biotic degradation on mechanical properties of PA6/MMT nanocomposites is presented.

Celem przeprowadzonych badań było otrzymanie nanokompozytów poliamidowych z różnym typem organicznie modyfikowanej glinki. Stabilność termiczna czystych glinek mierzono za pomocą analizy termograwimetrycznej (TGA). Otrzymane nanokompozyty zostały scharakteryzowane przy wykorzystaniu dyfrakcji promieni rentgenowskich (XRD) oraz spektroskopii w podczerwieni (IR). Zbadano również zmiany własności mechanicznych. Uzyskane wyniki potwierdzają dobrą interkalację nanonapełniaczy z matrycą polimerową, pokazując tworzenie struktur częściowo eksfoliowanych. Nanokompozyty wykazały wyższą stabilność termiczną w porównaniu do czystego poliamidu. Artykuł zamyka dyskusja związana ze skutkami degradacji biotycznej nanokompozytów PA6/MMT na ich właściwości mechaniczne.
