▎ 摘　　要

NOVELTY - A pleated graphene is prepared by mixing anhydrous ferric chloride with graphite, carrying out molten salt method, obtaining second-order graphite intercalation compound, adding oxidant and concentrated acid, performing oxidative intercalation, obtaining oxygen-containing group layer and ferric chloride intercalated graphite, adding aqueous solution, ultrasonicating, stripping oxygen-containing layer, obtaining iron chloride intercalated graphene oxide, dispersing in water, filtering, obtaining film, immersing in hydrogen peroxide aqueous solution, taking out, drying, repeating, and immersing in hydroiodic acid solution. USE - A method for preparing pleated graphene. ADVANTAGE - The method is simple, improves product wideness and uniformity, has low equipment requirements, and is suitable for industrial or experimental purposes.
