Preparation of Conductive Fine Flake Expanded Graphite/Polyaniline Composites
Conductive fine flake expanded graphite/polyaniline composites was prepared by emulsion polymerization with sodium dodecyl benzene sulfonate(SDBS) as emulsifying agent, ammonium persulfate as initiator, hydrochloride and fine flakeexpanded graphite as dopants. Effects of hydrochloric acid, dopant, emulsifier and initiator to the conductivity has also been found through orthogonal experiment. The best condition, under which the conductivity is over 2.0S/cm, is 6% doped graphite, 6ml hydrochloric acid, 5.00g emulsifier and 3.25g initiator. It also demonstrates the improvement of the conductivity of polyaniline (PANI) via addition of graphite.
