▎ 摘 要
NOVELTY - Gas phase physical stripping method of graphene powder involves selecting scaly graphite with high purity as raw material for producing graphene, mixing the scaly graphite and ball milling stripping medium into the ball mill, adding polyvinyl pyrrolidone, polyvinyl alcohol, oleic acid amide under the protection of inert gas for ball milling stripping after stripping and separating out the graphene sheet after ball milling and stripping by gas flow under the protection of inert gas. USE - Gas phase physical stripping method of graphene powder used for producing graphene used for anode of photovoltaic device. Can also be used in solar cell. ADVANTAGE - The graphene powder gas phase physical peeling method provides graphene sheet in the form of complete powder. The storage and use environment will not be limited, the industrial production cost is low, and it is convenient for graphene to be widely applied to each industry of each row. The graphene sheet has good fluidity, light weight, good strength, and is easy to fall off.
