▎ 摘　　要

A conductive network composed of reduced graphene oxide (RGO) planes and polyaniline (PANI) chains was designed and fabricated by in situ polymerization of aniline monomer on the RGO planes. It was further used for fabrication of conductive composites with a polymer matrix-ethylene vinyl acetate (EVA). The composites achieve improved conductivity at a low filler loading although the host polymer-EVA-is of insulator. For instance, compared to the pure EVA polymer, the conductivity of the composite filled with 4.0 wt.% RGO and 8.0 wt.% PANI increases from 1.2 x 10(-14) S cm(-1) to 1.07 x 10(-1) S cm(-1). In addition, thermal stability of the composites is also enhanced by the filler loading. (c) 2012 Elsevier Ltd. All rights reserved.
