摘要:
A surface-treated PFA film, wherein hydroxyl groups and carbonyl groups are present on the surface of the surface-treated PFA film. Further, the surface state of the surface-treated surface is a surface state having no irregularities, and preferably the average surface roughness is at most 10 nm. The surface treatment is carried out by RF or DC bombardment method, preferably in an Ar gas atmosphere.
