▎ 摘　　要

This article analyses research trials on noteworthy features and technological impact of the polystyrene/graphene nanoplatelet nanocomposites. In polystyrene matrix, graphene nanoplatelets have been used as remarkable nanofiller. Substantial improvements in polystyrene physical properties occurs by adding low nanofiller content. Simple in situ, emulsion, solution, or melt synthesis strategies have been used to develop polystyrene/graphene nanoplatelet nanocomposite. The polystyrene/graphene nanoplatelet nanocomposites possess enhanced structural features, morphology, glass transition temperature, thermal stability, mechanical strength, electrical characteristics, sensing, capacitance, and other physical properties. The performance of the polystyrene/graphene nanoplatelet nanocomposites have been explored for the practical applications in the fields of sensing, electromagnetic interference shielding, and flame retardant materials.
