▎ 摘  要

NOVELTY - Modified carbon monomer (CMC) water-phase stripping agent comprises deionized water and modified sodium carboxymethyl cellulose, where the mass fraction of the modified sodiumcarboxylic acid cellulose is 0.5-0.5 wt.%. USE - Water phase stripping agent used for preparing graphene for semiconductor industry, photovoltaic industry, lithium ion battery, aerospace and military fields. ADVANTAGE - The water phase stripping agent has excellent peeling effect, excellent environmental protection and economical efficiency, and provides graphene with large area and less layer number, by simple physical stripping method. The method uses water as main body, so the production cost is low and the harm to the environment is very small. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using aqueous phase stripper, which involves dispersing graphite powder in aqueous phase stripper to form a suspension, subjecting graphite powder to ultrasonic, and then grinding or high-pressure overflow impact exfoliating to obtain the single sheet or several sheets of superimposed graphene.
