Study of Ageing of Copper Foils in the Outdoor Environment
The ageing of copper foils and Copper foils-surfaced in UV rays are studied by 3D Video, SEM, EDX, which shows that copper foils and Copper foils-surfaced are in different level of ageing; embossment and crack which are the most obvious aging characteristics found by SEM, obviously, the ageing velocity of copper foil -surfaced is higher; The sulfur is found in the powder-like material around the embossment on the surface of copper foils by EDX, which indicates that sulfur is involved in the process of aging.
