在乙醇/水的混合溶液中,采用聚乙烯吡咯烷酮（PVP）为分散剂,偶氮二异丁腈（AIBN）为引发剂,通过分散聚合法制备出聚苯乙烯（PS）微球,然后以微球为模板,将产生的PS粒子作为核,SiO_2作为壳。SiO_2空心球通过在600℃时的热分解可得到。对制得的空心球通过热分析仪、扫描电子显微镜进行表征。对图进行分析,并讨论影响因素。

PVP as the stabilizer and AIBN as the initiator PS spheres were prepared in ethanol/water medium by dispersion polymerization method.Silica spheres which were composited with PS as a core and silica as the shell were prepared by using polystyrene（PS）as a templete.Hollow silica spheres are obtained in a following step by thermal degradation of the PS cores at 600 temperature.Thermogravimetric analysis and SEM were used to characterize the monodispersed hollow silica.Factors of influence were put forward and charts were analyzed.
