Abstract
Properties of polycarbonate and polycarbonate–TiO2 nanocomposite films were studied by X-ray diffraction analysis (XRD), FTIR spectroscopy, UV-Vis, and thermogravimetric analysis (TGA). The optical band gap values were found to reduce from 4.3 to 3.5 eV with increase in TiO2 content of nanocomposites. The influence of TiO2 nanoparticles in the polymer thermal degradation was determined by the Broido method and calculating the activation energy. The activation energy is higher for all nanocomposite compare with PC and it means higher thermal stability of nanocomposite. In addition TGA carves showed that nanocomposite films have higher resistance to thermal degradation compared to PC.
