Graphene Foam
Graphene foam is a threedimensional (3D) material composed of interconnected graphene sheets or layers. It combines the extraordinary properties of graphene—such as high electrical conductivity, thermal conductivity, mechanical strength, and surface area—with a porous structure that enhances its functionality in various applications. This innovative material has garnered significant attention due to its versatility and potential for revolutionizing industries ranging from energy storage to biomedical engineering.
