Physical Properties of Graphene Graphene is a single-layer nanomaterial consisting of carbon atoms, exhibiting outstanding mechanical strength, high electrical conductivity, and superior thermal conductivity. These properties make it an ideal candidate for manufacturing high-performance composites. Despite being only a few atoms thick, graphene’s surface area is equivalent to that of a football field.
2. Applications of Graphene in Resins 1. Reinforced Resin-Based Composites The incorporation of graphene significantly enhances the mechanical performance of resin-based composites, including tensile strength, flexural strength, and impact resistance. Through proper dispersion techniques, graphene can be uniformly distributed within the resin, yielding composites with both excellent mechanical and electrical properties.
