大分子在固/液界面的吸附行为及应用

Property and Application to the Absorption of Macromolecules at Solid-Liquid Interface-A Review

由于链状大分子(聚合物)结构的柔韧性和具有一定内旋自由度,所以当它们吸附于界面时,呈现出独特的性质。文章综述了大分子在固/液界面吸附时的概念、特征及影响因素,并对聚合物吸附的应用做了总结。

Chain-like macromolecules(polymers) show characteristic adsorption properties due to their flexibility and internal degrees of freedom when attracted to surfaces and interfaces.In this review,the paper I discuss concepts and features that are relevant to the adsorption of neutral and charged polymers at equilibrium,including the type of polymer/surface interaction,the solvent quality,the characteristics of the surface,and the polymer structure.I pay special attention to the case of charged polymers(polyelectrolytes) that have a special importance due to their water solubility.We present a summary of recent application in this rapidly evolving field.
