ESCA(或XPS-X光电子能谱)方法用于研究聚合物薄膜表面结构有其独到之处,因它不需破坏试样表面层而能直接提供有关的信息。如Riggs曾用ESCA研究了经钠/铵处理过的含氟聚合物表面结构,证明处理后的表面脱了氟,并存在不饱和的双键。Clark和Riggs等人研究了氟化聚乙烯薄膜的表面结构。Clark通过对能谱图形的解析及化学的定量计算,得出氟 The ESCA (or XPS-X photoelectron spectroscopy) method is unique in its investigation of the surface structure of polymer films because it provides direct information without breaking the surface layer of the sample. For example, Riggs used ESCA to investigate sodium / ammonium-treated fluoropolymer surface structures, demonstrating that treated surfaces de-fluorinated and that unsaturated double bonds were present. Clark and Riggs et al. Studied the surface structure of fluorinated polyethylene films. Clark through the analysis of the energy spectrum and chemical quantitative calculation, come to fluorine
