Two-dimensional conductor graphene have recently attracted attention due to in-plane mechanical, thermal, and electronic properties as well as its applications in future optoelectronic devices. Graphene sheets were produced by chemical reduction of exfoliated graphite oxides. But in the process of reduction, reduced graphite flakes agglomerate and eventually precipitate. This precipitated graphite flakes could not be re-dispersed by sonification in water containing surfactants. In this study, we synthesized stable aqueous dispersions of polymer-coated graphite sheets via reduction of graphite oxide in the solution of conductive polymer, poly(4-styrenesulfonic acid) and Nafion. The obtained graphite, coated with conductive polymer, had been characterized by FT-IR spectroscopy, UV-Vis, Thermogravimetric analysis (TGA) and High Resolution X-ray Diffractomer (HR-XRD). |
