Abstract:

The graphene and other carbon nanomaterials were mixed and ground with solvents and various additives to prepare a stable graphene composite conductive paste. This conductive paste was sprayed on the surface of acrylonitrile?butadiene?styrene copolymer (ABS) to provide excellent electrical conductance for ABS, followed by an electroplating treatment. To improve the bonding force between the graphene coating and the surface of ABS, different surface treatments were carried out for the ABS, which included the matte, organic solvent micro?corrosion and chemical roughening methods. The results indicated that the surface roughening treatments resulted in the formation of micropores on the plastic surface, leading to an enhancement in hydrophilicity. The chemical roughening method also produced some hydrophilic groups on the plastic surface, thus greatly improving the adhesion of the graphene coating. The ABS/graphene system presented good electrical conductance with a resistance range of 0.3~5 kΩ. The products obtained from electroplating exhibited good metal luster, and their coating layers were intact and not easy to fall off.

Key words: graphene, conductive paste, acrylonitrile?butadiene?styrene copolymer, surface treatment, electroplating
