XPS已被广泛应用于高聚物的研究,其中一个颇为重要的内容是研究嵌段共聚物和共混物的表面分相情形。在共聚(或共混)物的组份不互溶时,将会产生多相结构,高聚物表面会有某种低表面能组份的富集,同时这种富集与组份的分子量、组成和试样的热历史等有关。在溶液涂膜时,还与溶剂和温度有关。XPS是研究这种高聚物表面组成和形态变化的最有力工具之一。
XPS has been widely used in the study of polymers, and a very important one is to study the surface phase separation of block copolymers and blends. When the components of the copolymerization (or blend) are immiscible, a multi-phase structure will be generated, and the enrichment of some low surface energy components on the surface of the polymer will occur. At the same time, the enrichment and the molecular weight of the components, Composition and thermal history of the sample and so on. In solution coating, but also with the solvent and temperature. XPS is one of the most powerful tools for studying the surface composition and morphology of such polymers.
