摘要
[目的]研究镀液中羟乙基纤维素(HEC)质量浓度对不同厚度电解铜箔性能的影响。[方法]通过电镀制备了厚度分别为12、18和35μm的电解铜箔。研究了镀液中HEC质量浓度对不同厚度铜箔光泽度、粗糙度、组织结构及力学性能的影响。[结果]HEC质量浓度对35μm铜箔性能和组织结构的影响最大,对12μm铜箔的影响最小。电镀制备12、18和35μm铜箔时,宜将镀液的HEC质量浓度分别控制在5~10 mg/L、5~15 mg/L和5~10 mg/L范围内,以获得力学性能合格的铜箔。[结论]合理控制镀液添加剂浓度有利于获得力学性能优良的电解铜箔。
[Introduction]The effect of mass concentration of hydroxyethyl cellulose(HEC)on properties of electrolytic copper foil with different thickness needs to be studied.[Method]Electrolytic copper foils with different thickness were prepared by electroplating.The effect of mass concentration of HEC on glossiness,roughness,and microstructure at matte side,and mechanical properties of copper foils with different thickness were studied.[Result]The mass concentration of HEC had the greatest impact on the properties and microstructure of 35μm-thick copper foil,while the least influence on the 12μm-thick copper foil’s.It is recommended to control the mass concentration of HEC in the range of 5-10 mg/L for 12μm-thick copper foil,5-15 mg/L for 18μm-thick copper foil,and 5-10 mg/L for 35μm-thick copper foil with qualified mechanical properties.[Conclusion]Appropriate control of additive dosage in bath is favorable for preparation of electrolytic copper foils with excellent mechanical properties.
