▎ 摘  要

NOVELTY - Forming composite material involves photo-initiating a polymerization of a monomer in a pattern of interconnected units to form a polymer microlattice, removing unpolymerized monomer from the polymer microlattice, and coating the polymer microlattice with a metal. The polymer microlattice is then removed to form a metal microlattice. A graphitic carbon is deposited on the metal microlattice. The graphitic carbon is converted to graphene, and metal microlattice is removed to form a graphene microstructure. The graphene microstructure is dispersed in a polymer matrix. USE - Method for forming composite material. ADVANTAGE - The method provides regular structure with defined dimensions, form very thin metal (such as nickel, cobalt, copper, silver, or gold) microlattices, enables the formation of graphitic carbon on very thin metals by a surface-limited process for very thin metal wires or tubes. The electroless plating has multiple advantages over electroplating, free from flux-density and power supply issues, and provides an even deposit regardless of workpiece geometry, and with the proper pre-plate catalyst, and deposit on non-conductive surfaces.
