[0002] Electrolytic copper foil is an important electronic base material, which is a thin sheet of copper material with a thickness of several microns to tens of microns, usually prepared by reducing and depositing copper ions on the cathode in a special device by electrolysis. Sulfate solution is usually used as electrolyte, and appropriate amount of sulfuric acid and other additives are added to improve the conductivity and stability of the electrolyte. Titanium or stainless steel is used as the cathode, and pure copper is used as the anode. Under the action of direct current, copper ions are reduced and deposited on the cathode surface to form copper foil. In order to improve the performance of copper foil, surface treatment such as roughening, solidification, heat-resistant layer treatment, etc. is needed to enhance the adhesion and heat resistance between copper foil and insulating layer. After surface treatment, the copper foil needs to be cleaned, dried, and cut for post-processing to obtain finished electrolytic copper foil.
