摘　　要： 应用衰减全反射-傅立叶变换红外光谱技术(FTIR-ATR)分析三种不同类型复合材料成分,并运用扫描电镜和光电子能谱方法对结果进行了确证,确定了:1.复合材料密封膜HNP由聚丙烯、(乙烯-乙酸乙烯酯)共聚物和聚酰胺三层材料组成;2.纤维复合膜中间层的粘结材料为聚四氟乙烯;3.金属复合包装膜中聚合物材料为(偏二氯乙烯-丙烯酸酯)共聚物。实验表明FTIR-ATR技术在复合材料表层和夹层中高分子材料成分的分析应用中有明显的优势,简化了繁杂的分离纯化样品工作,方法简单、易于操作。文中对使用FTIR-ATR技术进行定性分析中的若干问题提出探讨。 Qualitative analysis method by using ATR- FTIR technique were used to analysis the chemical composition of three kinds of several layers polymer complex, the results were confirmed by using Scanning Electron Microscope and X - ray Photoelectron Spectroscopy, The result showed： 1. The chemical composition of each layer of the HNP film are polypropylene, ethylene - vinyl acetate copolymer and polyamide; 2. The structure of adherence layer material of fibrous film was polytetrafluoro ethylene; 3. The polymer composition of metal- polymer film was vinylidene flouoride - acrylate copolymer ; The experiments showed that the advan- tage of ATR- FTIR＇s application on analysis of polymer surface composition is obvious, it simplifies the complexity works on sample＇s separation and purification, the method is simple and easily operate. Some technical problems on ATR experiment are discussed.
