Physicomechanical properties of nano polystyrene nanocomposites

Abstract

PREPARATION of nano metal oxides (Fe2O3, ZnO and TiO2) and nano sphere polystyrene (PS) has been done in micellar solution. Nanocomposite films have been prepared by doping nano polystyrene with different ratios of nano metal oxide ranged from 0.25 up to 3 wt%. These nanocomposites were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR).Thermo gravimetric analysis (TGA) and mechanical properties have also been investigated. By comparison with the values obtained for the PS, it was observed that the thermal stability is higher for the nanocompoistes and increases with increasing the nano metal oxides concentration in these samples. The results indicate that the tensile strength, elongation at break and Young's modulus of all the nanocomposites enhanced with the addition of metal oxides nanoparticles compared with the pure PS.
