▎ 摘　　要

NOVELTY - Graphene composite sheet comprises a first functional film (100) comprising a functional material having conductivity as a main component, a protective film attached to both surfaces of the first functional film to prevent the first functional film from being damaged, a second functional film (300) provided on one of both surfaces of the protective film and includes a conductive material different from the main component of the first functional film. The first functional film is made of graphite, fullerene, and carbon nanotube having carbon as a main component. The protective film for preventing damage to the first functional film on both sides of the first functional film is PET (Polyethylene Terephthalate), PU (Polyurethane) and PI (Polyimide). USE - Used as a graphene composite sheet. ADVANTAGE - The graphene composite sheet has waterproof function; improves thermal conductivity, and effect of shielding electromagnetic waves. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of graphene composite sheet. First functional film (100) Second functional film (300)
