▎ 摘　　要

In this study, graphene/polystyrene nanocomposites were first obtained by Pickering emulsion polymerization technique. The results showed that the thermal, mechanical, and conductivity properties of polystyrene were remarkably improved at low loading of functionalized graphene. In fact, the functionalized graphene could not only be use as an effective solid stabilizer for styrene-in-water Pickering emulsion but also be dispersed homogeneously into the production of polystyrene as highly effective nanofiller using this method. The superior properties of the graphene/polystyrene composites are the result of good dispersion of functionalized graphene in the polystyrene matrix.
