▎ 摘　　要

NOVELTY - Manufacturing a plastic card formed with a graphene-antenna comprises (S210) preparing a colloidal solution including graphene, (S220) preparing a graphene ink component by mixing the colloidal solution, water-dispersible polyurethane solution, and the crosslinking agent, (S230) preparing an antenna sheet having a graphene-antenna by forming a closed circuit antenna on the plastic sheet layer using the graphene ink and fixing the closed circuit antenna to the plastic sheet layer by a cross-linking reaction, and (S240) laminating the antenna sheet including the graphene-antenna with transparent plastic sheet layers to complete a plastic card. USE - The method is useful for manufacturing plastic card with a graphene-antenna (claimed). ADVANTAGE - The method: provides flexible plastic card as the antenna for a closed circuit including a graphene component has a high electrical conduction path. The plastic card with a graphene-antenna: has high thermal conductivity; has excellent mechanical strength, elasticity, and transparency; and can be produced in large quantity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for plastic card with a graphene-antenna manufactured by the above mentioned method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram illustrating a method for manufacturing plastic card formed with a graphene-antenna (Drawing includes non-English language text).
