摘要: Perfluorosulfonic acid membrane (Nafion®-117) was first surface modified with atmospheric pressure UV photo-oxidation or low-pressure vacuum downstream from an Ar microwave plasma, and then graft polymerized acrylic acid. X-ray photoelectron spectroscopy (XPS) used to analyze the Nafion poly(acrylic acid) grafted surface.
