▎ 摘  要

NOVELTY - A graphene paper collector preparing method involves performing an oxidation reaction on graphite with potassium permanganate and concentrated sulfuric acid to obtain oxidized graphite. The oxidized graphite is mixed with solvent to prepare oxidized graphite solution, which is ultrasonically stirred to obtain uniformly dispersed graphene oxide suspension liquid. The suspension liquid is placed into a reaction kettle to react to obtain graphene suspension, which is vacuum-filtered using micro-porous filtering film and dried to obtain graphene paper. USE - Method for preparing graphene paper collector. ADVANTAGE - The method enables preparing graphene paper collector with high conductivity. DETAILED DESCRIPTION - A graphene paper collector preparing method involves performing an oxidation reaction on graphite with potassium permanganate and concentrated sulfuric acid to obtain oxidized graphite. The oxidized graphite is mixed with solvent to prepare oxidized graphite solution. The oxidized graphite solution is ultrasonically stirred to obtain uniformly dispersed graphene oxide suspension liquid. The suspension liquid is placed into a reaction kettle to react to obtain graphene suspension. The graphene suspension is vacuum-filtered using micro-porous filtering film to obtain filtrate. The filtrate is dried to obtain graphene paper. The graphene paper is treated in an atmosphere of inert gas at 500-1000 degrees C to carry out reduction reaction to obtain reduction reaction product. The product is cooled to room temperature to obtain a finished product.
