摘　　要：采用悬浮聚合法以正硅酸乙酯(TEOS)和γ-甲基丙烯酰氧基丙基三甲氧基硅烷(MPS)为主要原材料,制备表面功能化的单分散聚硅氧烷微球。采用扫描电镜(SEM)、动态光散射(DLS)和红外光谱(FT-IR)等分析手段分别对功能性微球的微观形貌、粒径分布和微观结构进行表征。将这种表面功能性的单分散聚硅氧烷微球按照0.4%的添加量加入光学级聚碳酸酯(PC)树脂中,可制备出透光率75.6%、雾度94.6%性能优良的光散射材料。Surface functionalization and monodisperse polysiloxane microspheres were prepared by the suspension polymerization from tetraethyl orthosilicate （TEOS） and methacryloxy propyl trimethoxyl silane （MPS）. The morphology, size distribution and structure was characterized by SEM, DLS and FT-IR. Light scattering material could be prepared by blending surface functionalization and monodisperse polysiloxane microspheres with optical-grade polycarbonate （PC）. When the mass fraction of microspheres was about 0.4%, the transmittance of light scattering material was 75.6% and the haze was 94.6%.
