Abstract
A method of manufacturing a graphene oxide composite fiber includes forming a supporting fiber having positive charges thereon; forming a solution containing graphene oxide having a negative charge thereon to provide a graphene oxide-containing solution; coating the supporting fiber with the graphene oxide-containing solution; and permitting self-assembly of the graphene oxide of the graphene oxide -containing solution and the supporting fiber by an attraction between the positive and negative charges to form the graphene oxide composite fiber. The method may include coating the supporting fiber with a solution containing a material having an amine group to provide a positive surface charge on the supporting fiber. The method may include reducing the graphene oxide composite fiber to a graphene composite fiber, such as by one of a thermal reduction method, an optical reduction method, and a chemical reduction method. Large-area graphene fiber structures having high strength, flexibility, and porosity are enabled.
