Abstract
Graphene fibers made from a graphene film formed into an elongated fiber-like shape and composite materials made from the graphene fibers. The graphene film has amine groups formed on at least an outer surface of the graphene film and epoxide groups formed on at least one edge of the graphene film. The amine groups are formed in a functionalized area on the outer surface of the graphene film that is within about 10 microns from the at least one edge of the graphene film, or the functionalized area may extend the entire width of the graphene film. The graphene film may also have holes formed through the graphene film. The elongated fiber-like shapes may be the graphene film in a rolled spiral orientation or the graphene film in a twisted formation.
