Abstract:With the development of high-end industries, such as 5G communications and new-energy vehicles, the higher requirements for the capabilities of electrolytic copper foil products were put forward. Using an extremely important technology, the electrolyticcopper foil surface treatment is regarded as a primary way for solving copper foil green production problem and obtaining high performance coating copper foil. Here, the present domestic and foreign research status of copper foil surface treatment including coarsing process, curing process, alloying process, passivation process, silanization process, etc, were documented and summarized. Especially, the composition of the electrolyte in each process and the influencing factors of electrodeposition were presented and analyzed, respectively. Moreover, we reviewed the research status and classification of additives in coarsening progress, and emphasized the mechanism of each additives including grain refiner, leveling agent, brightener, surfactant and inorganic additive, as well as the effects of additives on morphology and properties of copper foil. Finally, the future development direction of copper foil in China was pointed out. We believe that this review will provide a reference for our country independent development of high-performance copper foil production technology.
