Alteration of contact properties and chemical structure of polyethersulfone film surface by direct-current discharge treatment

详细

Changes in the contact properties of the surface of polyethersulfone films modified at the cathode and the anode by dc discharge with varying the treatment time and discharge current have been studied. It has been shown that the treatment imparts hydrophilicity to the films, which persists for a long time. The chemical composition and structure of the surface of the modified films has been examined using X-ray photoelectron spectroscopy.
