Preparation and Characterization of Titanium Dioxide/ Poly(methyl Methacrylate) Composites by In-Situ Polymerization
Asian Journal of Chemistry/Asian journal of chemistry(2013)
摘要
Anatase titanium dioxide (TiO2) particles were obtained by sol-gel method and modified with saline coupling agent. TiO2/poly(methyl methacrylate) composites were prepared via in situ bulk polymerization of methyl methacrylate, in which modified TiO2 particles were dispersed uniformly. SEM micrographs showed that TiO2/poly(methyl methacrylate) composites exhibited favourable miscibility behaviour, even at high content of TiO2 (0.7 wt %). Moreover, incorporation of TiO2 particles can improve mechanical and thermal stability of poly(methyl methacrylate) significantly.
