【摘要】 为了提高胶粘剂、有机涂层、缓蚀剂的性能,了解高聚物/金属界面的结构和性能是非常必要的。目前常用的表征表面的方法直接测定界面层结构尚有困难,因为界面层不能孤立出来直接研究。着重介绍了与有机膜层/金属粘接界面相关的表征方法。衰减全反射红外光谱(ATR-IR)不仅能分析高聚物表面结构信息,还可分析不透明的材料表层及含水材料信息。反射吸收红外光谱(RA-IR)则对研究金属表面涂层分子取向、金属表面化学反应比较有效。X射线光电子能谱(XPS)能较好地表征金属与高聚物间的相互作用。拉曼光谱法与电化学方法相结合可以原位表征金属表面在分子水平上的信息。通过比较认为FTIR与XPS相结合是相对理想的表征界面的方法。更多还原

【Abstract】 In the study of anticorrosion coating,adhesive and corrosion inhibitor on the metal surface,it is important to know the structure and performance of the interface of polymer/metal. Now it is difficult to characterize the formation of the interface layer directly, for the interface layer can′t be separated to be studied directly. In this paper, it introduces some techniques which are correlated with the adhesive interface of polymer/metal. ATR-IR can analyze the structure information of the polymer surface and untransparent material and hydrous material. RA-IR can study the molecular orientation and chemical reaction of the coating on metal surface. XPS can analyze the chemical reaction on interface through the change of binding energy. RAMAN can in situ.show the message at the level of molecule. Though these methods are commonly used in polymer surface, they are also helpful to study interface.更多还原
