- Surface Modification of Tetrafluoroethylene-Perfluoroalkyl Vinyl Ether Copolymer by Excimer Laser Irradiation.
抄録
Tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA) in contact with dilute ammonia aqueous solution was endowed with surface wettability by excimer laser irradiation. ArF-laser was more effective than KrF for the surface modification. The water contact angle of the PFA film decreased from 106° to 31°by ArF-laser irradiation with 203 J cm-2. X-ray photoelectron spectroscopy (XPS) spectra indicated loss of fluorine atoms and introduction of nitrogen and oxygen atoms on the PFA surface, induced by a photochemical reaction. The atomic ratios estimated by XPS measurements were closely related to the contact angles with water. From the angular dependence of the F/C atomic ratio of an irradiated PFA film, the thickness of the modified layer was estimated to be 1.5-7.0 nm. No morphological change in the modified PFA surface was observed with a scanning electron microscope (SEM).
