摘要：

The nano rutile titanium dioxide (TiO2) was prepared through sol-gel method and poly (styrene) (PS) was grafted onto the surfaces of the prepared nano TiO2 via atom transfer radical polymerization (ATRP) method. Then, modification of styrene-butadiene-styrene block copolymer (SBS) with the resulted nano TiO2-g-PS composite particles was studied. The results of Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and transmission electron microscope (TEM) show that the PS macromolecular chains are successfully grafted onto the surfaces of nano TiO2. Through the measurements of mechanical properties, dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA), the mechanical property and thermal stability of SBS/TiO2-g-PS composites are better than those of pure SBS and SBS/TiO2 composites. After UV aging test, the mechanical property retention rate of SBS/TiO2-g-PS composites is superior to that of pure SBS and SBS/ TiO2 composites. © 2017, Editorial Board of Polymer Materials Science & Engineering.
