▎ 摘　　要

NOVELTY - Graphite oxide is added to solvent, stirred, sonicated and added to dispersant, to obtain graphite oxide suspension. The obtained suspension is mixed with hydrazine hydrate and reacted at 80-100 degrees C, to obtain graphene suspension. The obtained product is filtered using microporus membrane vacuum filtration and obtained cake is dried, to obtain graphene film. Reduction reaction of obtained product is performed at 500-1000 degrees C, to obtain graphene paper. USE - Manufacture of graphene paper used for current collector. ADVANTAGE - The method efficiently provides graphene paper having high conductivity.
