摘要
Abstract
Titanium dioxide nanoparticle size was calculated by transmission electron microscopic technique. Polypropylene/titanium dioxide nanocomposites were prepared using 0~3 wt% of titanium dioxide by melt mixing. It was then compression moulded in to films at 180℃. Thermal ageing was carried out in an air oven at 100℃ for 24 h. Mechanical properties of the samples were determined before and after thermal ageing. Infrared spectroscopy was used to study the degradation products. Morphology of the tensile fractured surfaces was analysed using scan-ning electron microscope showed stability of polypropylene/titanium dioxide nanocomposites after thermal ageing. Good dispersion of titanium dioxide in the PP matrix was evident from SEM images. Thermogravimetric analysis of the samples indicated that thermal stability of PP was increased by the addition of titanium dioxide.关键词
