As the most basic performance of copper foil, the appearance quality of copper foil must meet the requirements of customers. In the production process of copper foil, copper foil nail print as a common defect of copper foil appearance quality affects the appearance quality and economic benefit of copper foil product.

[0003] Therefore, it is very important to improve the appearance quality of copper foil and reduce the copper foil surface nail print. The main reason for the generation of copper foil surface nail print is that the additive formula involves sodium propane sulfonate compound. The compound is an anionic surfactant, which is easy to foam. When the solution of the surfactant is stirred, air or electrolysis gas is divided and wrapped by the liquid film containing the surfactant. At this time, the hydrophobic group of the surfactant is directed to the gas, and the hydrophilic group is directed to the solution. When the foil is electrolyzed, the generated bubbles float to the surface of the electrolyte, and the oriented molecular adsorption layer of the surfactant on the liquid surface is adsorbed, forming a double-layer surfactant molecular liquid film surrounding the bubbles. When the bubbles on the liquid surface contact the cathode roller, the surfactant is adsorbed on the cathode roller, and the surface is deposited on the anode tank to generate copper foil, which may have nail print.
