All aliphatic starting reactants were used to prepare two series of polycarbonate-based polyurethane (PC-PU) composite films: 1) with a low amount of titanium dioxide nanoparticles (0.5, 1.0 and 2.0 wt%) by one-step technique and 2) PC-PU hybrid materials by addition of submicron amorphous SiO2 Sidistar T120 particles (0, 1, 2, 5 and 10 wt%) using prepolymerization method. The study of the influence of different filler distribution on the structure of obtained elastomers composites was performed using FT-IR and AFM. TGA analysis was carried out to investigate the effect of inorganic fillers on thermal stability and degradation of synthesized PC-PU materials. The impact of silica and titania on the glass transition temperature and melting of obtained polyurethane systems was studied by DSC and MDSC. Based on obtained results, the synthesized polyurethane materials showed improved thermal stability and enhanced thermal properties.
