摘　　要：在乙醇/氨水介质中,以分散法制备的聚苯乙烯微球为模板,通过乙烯基三乙氧基硅烷水解缩合反应在聚苯乙烯表面形成包覆层.然后将聚苯乙烯球核溶解而制备了乙烯基化二氧化硅空心微球.In this paper,we adopt a facile method to prepare vinyl functionalized hollow silica spheres.In this approach,the polystyrene microspheres prepared by dispersion polymerization were used as the template microspheres,vinyl functionalized silica shells were then coated on the polystyrene microspheres by hydrolysis and condensation of vinyltriethoxysilane.The polystyrene microspheres were dissolved subsequently in the tetrahydrofunan to form monodispersed vinyl functionalized hollow silica spheres.
