This is very convenient graphene can be directly placed in a copper etching liquid (may be an ammonium sulfate solution and ferric chloride solution, an aqueous solution of hydrochloric acid through the copper sulfide, etc.) where the copper is etched away, and then transferred into deionized water rinse off the etching solution can be used.
