摘　　要：选用硫酸高铈为添加剂,运用电化学工作站、扫描电子显微镜(SEM)等手段探究了其在电解铜箔过程中的作用机理及其最佳添加量。研究表明,1 g/L的硫酸高铈添加量为2 mL时,电解铜箔的电位负移,晶粒细化,显著提高了抗腐蚀能力,粗糙度降低了近30%,抗拉强度和伸长率分别提高了65.1%和113.2%。铈阳离子的特殊电子结构,使其在电解铜箔生产过程中能够发挥优异作用,也为新型添加剂的开发提供了思路。Using cerium sulfate as additive,the operation mechanism and optimum dosage of cerium sulfate in copper foil electrolysis were investigated by means of electrochemical workstation and scanning electron microscope(SEM).The results show that when the amount of 1 g/L cerium sulfate is 2 mL,the electrolytic copper foil has negative potential shift and fine grain,which significantly improves the corrosion resistance,reduces the roughness by nearly 30%,and increases the tensile strength and elongation by 65.1%and 113.2%,respectively.The special electronic structure of cerium cation enables it to play an excellent role in the production of electrolytic copper foil,and also provides ideas for the development of new additives.
