Abstract
Nano-TiO2 was surface treated with a liquid titanate coupling agent. The melt-blending process was discussed with a torque rheometer. Some of the properties of nano-TiO2 and TiO2/polystyrene (PS) nanocomposites were characterized using fourier transform infrared spectroscopy (FT-IR), and differential thermal and gravimetric analysis (DTA-TG). The results showed that the methodology of the nanocomposite was obviously changed after filling the treated or untreated nano-TiO2, and the unnotched impact strengths of the nanocomposites were increased with nano-TiO2 content. Surface treatment of nano-TiO2 generally yielded nanocomposites of higher impact strength than untreated system.关键词
