▎ 摘 要
NOVELTY - Producing carbon paper comprises (1) mixing cellulose fibers and graphene in water according to a predetermined ratio and adding a crosslinking agent or binder, (2) filtering cellulose fiber/graphene solution obtained in step (1) or floating on paper, (3) drying and compressing cellulose fiber/graphene paper, and (4) heat treating and carbonizing cellulose fiber/graphene paper. USE - The carbon paper is useful for manufacturing electromagnetic wave shielding sheet (claimed) for smartphones, wearables, the Internet of Things, and automobiles. ADVANTAGE - The carbon paper: has good flexibility and electrical conductivity; prevents malfunctions of electronic devices and signal quality deterioration; and is light weight and environmentally friendly. The method is simple and does not use metal material.
