摘要：Sulfonated Graphene (GS) is a kind of ideal conductive filler due to its excellent electrical conductivity, large specific surface and high dispersion. However, it usually has a tendency to agglomerate in polymers which seriously weaken the antistatic property. Herein, a novel conductive filler was fabricated in a simple and low-cost method by self-assembling GS nanosheets onto the surface of BaSO4 nanoparticles (BaSO4@GS) through electrostatic attraction. The morphology, microstructural composition and antistatic property were studied. The conductive BaSO4@GS particles have greatly dispersion in the epoxy resin matrix and significantly decrease square resistance of coating. The results show that the addition of 2 wt% (GS content in the epoxy composite) BaSO4@GS nanoparticles can decrease sheet resistance to 32 K Omega/sq. We attribute this enhancement in conductive performance of the epoxy composite to construction of the conductive networks for BaSO4@GS additives. Thus, the conductive fillers show the great potential for application in the petrochemical industry.
