Abstract

In recent years, numerous scientists have used graphene for reinforcing polymer-based composites because of its outstanding electrical, thermal and mechanical properties. Based on this present reported work, a simple manufacturing process is reported for the fabrication of low-loading graphene nanosheets (GNSs) coated on the surface of a polypropylene matrix. According to a scanning electron microscope micrograph, the GNSs were dispersed uniformly on the surface of polypropylene pellets. The mechanical properties and thermal stability of the GNSs /polypropylene composite plates were improved substantially by the addition of GNSs. X-ray diffraction was used to determine that the two-theta values of the GNSs /polypropylene composite plates correspond to the weight fraction of the added GNSs. Fourier transform infrared spectroscopy revealed that the vibration peak of the polypropylene methyl group decreased gradually when the amount of GNSs increased.
