Abstract

Emulsion gels are systems which are similar to emulsions in composition, but also similar to gels in viscosity and stability. In the presence of the cationic surfactant CTAB, emulsion gels of styrene and fumed silica formed with water. In-situ free radical polymerization was carried out in emulsion gels at room temperature by surfactant-assisted initiation. Roughly mono-dispersed spherical nano-particles were obtained. Thermal analysis showed that the silica particles were covered by a thin layer of CTAB, followed by CTAB multilayers and then a mixed PS-CTAB coating. The stabilized emulsion gels made it possible to obtain hybrids of uniform composition without stirring.
