▎ 摘　　要

A novel method of Pickering emulsion polymerization stabilized by graphene oxide (GO) and the role of adding salt (NaCl) were first described here. The ability of GO lower the interfacial tension and the effect of adding salt (NaCl) on particle adsorption at the oil-water interface were studied. It was found that GO nanosheets adsorbed effectively at the oil-water interface in salt solution and stable Pickering emulsion could be created. After the Pickering emulsion polymerization of styrene, the PS/GO nanocomposites were prepared successfully. The nanocomposites were characterized by transmission electron microscopy (TEM) and atomic force microscopy.
