Abstract

Acrylonitrile butadiene styrene (ABS) is a desirable engineering plastic due to its outstanding properties including good processing characteristic, good mechanical properties, chemical resistance and is relatively low cost. However, having an insulating behaviour restricts its application in electrical and electronic products. With the aim to increase the conductivity of ABS, a conducting material, in this case, graphene was incorporated. Mixtures of ABS and graphene were prepared by varying the weight of graphene and their electrical and mechanical properties were measured using Electrochemical Impedance Spectroscopy, (EIS), universal testing machine, pendulum impact and field emission scanning electron microscope (FESEM). From the results, improvement of conductivity and mechanical (tensile and flexural strength) properties of ABS-graphene composite is shown by higher amount of graphene. These enhanced properties can be related to good dispersion and intimate interaction of graphene platelet and ABS matrix as confirmed by electron microscopy image
