Preparation of graphene and its application in polycarbonate/acrylonitrile-butadiene-styrene composites

Abstract Graphene was prepared by the reduction of graphene oxide through chemical, thermal, and microwave methods. The morphology and structure of graphene obtained using different reduction processes have been characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Raman spectra. Polycarbonate/acrylonitrile-butadiene-styrene copolymers were modified with the addition of the as-prepared graphene. Electrical resistivity and tensile strength as well as thermal stability of composites have been investigated. The results reveal that graphene from chemical reduction is well compatible with composites and suitable for the enhancement of thermal stability. Graphene prepared from thermal reduction and microwave reduction are applicable for mechanical reinforcement and antistatic fields, respectively.
