Abstract

Monodisperse anisotropic poly(styrene-co-divinylbenzene) (PS-DVB) particles with single cavity structures were synthesized using a modified dispersion polymerization method. The effects of DVB adding modes and speeds on the particle morphologies were studied. Using the PS-DVB cave particles as templates, monodisperse anisotropic silica (SiO2) hollow microspheres were fabricated facilely. The obtained anisotropic silica hollow spheres had a potential application in rapid waste removal and detoxification extraction with a very simple procedure.
