摘要

我们研究了平面与污染物溶液之间的相互作用。表面受到接枝聚合物层的保护。我们的主要兴趣在于通过分子扩散,更好地理解和阐明简单的分子相互作用对表面污染和净化的影响。这些相互作用表现为污染物分子在接枝聚合物层上扩散时的平均力势。为简单起见,我们认为所有的相互作用都属于硬球类型。污染物分子的大小与溶剂和单个聚合物段的大小相同。尽管进行了这些简化,但该分析提供了重要的物理启示,并对污染和去污过程进行了定性描述。

Contamination and Decontamination of Polymer-Coated Surfaces
We study the interaction between a flat surface and a contaminant solution. The surface is protected by a grafted polymer layer. Our primary interest is to better understand and elucidate the effect of simple molecular interactions on the contamination and decontamination of the surface through molecular diffusion. These interactions manifest themselves in the potential of mean force that the contaminant molecule experiences as it diffuses across the grafted polymer layer. For simplicity, we consider that all interactions are of the hard-sphere type. The size of the contaminant molecule is the same as that of the solvent as well as the individual polymer segment. Despite these simplifications, the analysis offers important physical insights and a qualitative description of the contamination and decontamination processes.
