| abstract |
Composite prepreg materials made from a plurality of layers of graphene film having a size that spans an entire width and an entire length of the composite prepreg material, each of the layers of graphene film being functionalized with holes formed through the graphene film, amine groups formed on both an upper and a lower surface of the graphene film, epoxide groups formed on at least one edge of the graphene film, amine monomers and/or epoxy monomers. The plurality of layers may be formed by stacking a plurality of layers of graphene film to form a stacked composite prepreg material or by folding a graphene film to form a crumpled composite prepreg material. |
