How about Classification and Application Overview of Graphene Composite Materials
Graphene composite materials are a class of advanced materials that combine the exceptional properties of graphene with other materials, resulting in composites with enhanced performance. These composites can be classified based on the matrix material into which graphene is incorporated. The main categories are polymer matrix composites, metal matrix composites, ceramic matrix composites, and others. Here’s an overview of their classification and applications:
Classification of Graphene Composite Materials
1.Polymer Matrix Composites (PMCs)
Thermoplastic Composites:Graphene is incorporated into thermoplastic polymers like polyethylene, polypropylene, or polystyrene. These composites are known for their lightweight, flexibility, and improved electrical conductivity.
Thermoset Composites:Involves thermoset polymers such as epoxy, polyester, or phenolic resins. These composites offer enhanced mechanical strength, thermal stability, and durability.
2.Metal Matrix Composites (MMCs)
