▎ 摘　　要

NOVELTY - The sheet has a coating film that is formed on one side of a functional protective film that is bonded to a functional film. A magnetic material is formed on another surface of the protective film, and a functional coating film or a functional pattern is provided with an auxiliary functional material that contains copper. The coating film has a waterproof function, and the coating film is coated on a surface bonded to the functional film among both surfaces of the protection film. The protective film is made of a fabric material to prevent damage. USE - Multifunctional graphene composite sheet for use as outer skin of device in contact with human body, including heating mat. ADVANTAGE - The multifunctional graphene composite sheet has excellent thermal conductivity, electromagnetic wave shielding effect and far-infrared radiation effect, and is manufactured economically. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of multifunctional graphene composite sheet. (Drawing includes non-English language text) Functional film (100) Protective film (200) Coating film (210)
