摘要：
nano-SiO2 modified core-shell polyacrylate composite emulsion was synthesized by seeded semi-continuous starved pre-emulsion polymerization and sol-gel technique. The influence of 3-methacryloxypropyltrimethoxysilane(KH-570), tetraethoxysilane(TEOS) on the properties of emulsion and film were studied. The SiO2/silicone polyacrylate composite latex and the resultant films were characterized by fourier transform infrared spectroscopy(FT-IR), differential scanning calorimeter(DSC), thermogravimetric analysis(TGA), water contact angle goniometer (WCAG). The results showed that organic silicon and nano-SiO2 were effectively grafted to the polyacrylate molecular chain. We can observed there are two glass transition temperatures (Tg) in the DSC curve. The water contact angle (WCA) on the PAE film and SSPAE film separately attained 62.5 degrees and 85.5 degrees.
