Miniemulsion polymerization of styrene in the presence of graphite nanosheets

摘要

Miniemulsion polymerization of styrene was performed in the presence of carbon nanosheets. As a result, PS particles were introduced onto the surface of graphite nanosheets by the miniemulsion polymerization. The formation of SDS surface micelles is influenced by the concentration of graphite nanosheets. Therefore, the composites show three different surface morphologies of graphite nanosheets surfaces; (1) the surface attached with PS particles, (2) the surface covered with PS thin film, and (3) the bare exposed surface. The crosslinked PS particles strongly stick to the surface of graphite nanosheets and the graphite nanosheet/ crosslinked PS composites show much improved dispersion stability in toluene.
