ABSTRACT: Polycarbonate is a transparent commercial engineering polymer used in many applications especially in mobile protector screen for its good properties. In the present paper, nano composite material composed of polycarbonate sheet and nano titanium dioxide particles was prepared. Three ratios of TiO2 (0.01-0.03-0.05 g) were employed with polycarbonate by using pressing technique. Different mechanical, chemical, thermal and morphology tests were characterized as hardness, impact, FTIR, UV,XRD, DSC, tensile strength, contact angle and smoothness test. The results were shown that the hardness decreased in about 15% and the impact resistance increased in about 10% with TiO2 level increasing. FTIR showed there were no new peaks appearing and that indicated physical interactions between the nano filler and the polycarbonate matrix, also transparency reduced in about 5%. UV showed the absorption of polycarbonate to radiation after added TiO2. DSC showed decreasing in the Tg level and increasing in the crystallinity of material after processing. Contact angle test showed that the wettability increased at first but retained decreasing with adding more TiO2 to the surface. Surface roughness test and AFM test show decrease in smoothness with adding TiO2 to polycarbonate sheet.
