NOVELTY - Performing zero emission and pollution-free graphene chemical copper plating involves configuring copper sulfate solution and then slowly adding sodium potassium tartrate solution in the copper sulfate solution, where the molar ratio of potassium sodium tartrate to copper sulfate is 1.4-5:1, and then stirring to obtain gelatinous mixture. The strong alkali solution is added to the gel-like mixture and adjusting the pH to 12-12.5, and stirring to obtain mixed solution. The graphene suspension is added to distilled water after washing and dispersing and adding the mixed solution to the graphene suspension to obtain initiator solution. The formaldehyde solution is added to the initiator liquid, and formaldehyde and copper sulfate are mixed in the molar ratio of 2-2.5:1, stirring to obtain reducing solution. The copper powder is added as a catalyst to the reducing liquid and stirring to obtain reaction liquid. USE - Method for performing zero emission and pollution-free graphene chemical copper plating. ADVANTAGE - The method enables to perform zero emission and pollution-free graphene chemical copper plating , which improves the graphene to enhance performance of copper-base composite material and the graphene, causes less waste, pollution discharge, and is ecological and environment-friendly. DETAILED DESCRIPTION - The strong alkali solution is added to the reaction solution obtained to adjust the pH to 12-12.5. The formaldehyde solution is added to the remaining mixed solution in the molar ratio of 1.8-2.2:1, and stirring to obtain additive liquid. The obtained additive liquid is added to the reaction liquid and the pH of the reaction liquid is maintained at 12-12.5, and formaldehyde is added dropwise until the reaction liquid no longer appears blue, and the reaction is completed. The reaction solution is filtered to obtain copper-plated composite powder, which is rinsed, dried and stored after the completion of the reaction. The filtrate obtained in is used as a solvent, and the above steps are repeated to realize continuous copper plating of graphene. The strong alkali solution is added to the reaction solution obtained to adjust the pH to 12-12.5, and the reaction occuring is copper ions (Cu2+) + formaldehyde (HCHO)+ hydroxyl ions (3OH-)=copper precipitate (Cu) +formate ions (HCOO-)+ water (2H2O) and the side reaction is formaldehyde (HCHO)+ OH-=HCOO-+ hydrogen (H2).
