DescriptionAcrylonitrile butadiene styrene (ABS) is a common thermoplastic polymer used in engineering, electrical, textile, and automotive industries. ABS has good impact resistance and toughness but suffers from low flexural modulus and strength. Typically, ABS is mixed with other materials to create a composite with better properties. In this work, graphite was exfoliated into graphene nanoflakes (GNFs) within ABS in concentrations of 1, 5, and 20 wt.% GNFs followed by injection molding to fabricate GNF-ABS specimens for testing. The morphology and structure of the GNF-ABS composites were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy. And X-ray photoemission spectroscopy (XPS). The mechanical properties in flexure and electrical conductivity of the GNF-ABS composites were also determined. Results show that GNF particles created within ABS are multilayer graphene, and that increasing GNF concentration increases flexural modulus and strength, as well as impart electrical conductivity.
