Abstract:

Novel organic-inorganic nanocomposites based on thermostable polycyanurate networks (PCNs) and epoxy functionalized polyhedral oligomeric silsesquioxanes (POSS) with different content of epoxy groups were synthesized by the in situ formation and characterized. The influence of nanofiller’s content and type on thermal and thermal oxidative stability of nanocomposites prepared have been studied using thermal gravimetric analysis (TGA). It was found, that thermal and thermal oxidative stability of PCN/POSS nanocomposites varies depending on the content and type of nanofiller. The inhibition of thermal and thermo-oxidative degradation at temperatures < 470 °C for most nanocomposites synthesized and improvement of fire resistance of film materials have been established.
