, Zhejiang University3. College of Electrical Engineering, Zhejiang University摘 要:Smooth and strong copper foils are highly required for the development of printed circuit boards and Li-ion batteries. Adding additives is an efficient and low-cost method to enhance electrodeposited copper foils. Here we chose Bis-(3-sulfopropyl)-disulfide(SPS......

="ChDivSummary">Commercial grade rolled and electrodeposited copper foils from Japan and China were selected, and their mechanical properties and microstructure were investigated.It was observed that there are notable differences in fracture strength, elongation at break and hydrophilicity between rolled and electrodeposited copper foils. The rolled copper foils have higher tensile strength, lower......
