The classic Born model can be used to predict salt partitioning properties observed in hydrated polymers, but there are often significant quantitative discrepancies between these predictions and the experimental data. Here, we use an updated version of the Born model, reformulated to account for the local environment and mesh size of a hydrated polymer, to describe previously published NaCl, KCl, and LiCl partitioning properties of model cross-linked poly(ethylene glycol) diacrylate polymers. This reformulated Born model describes the influence of polymer structure (i.e., network mesh size and its relationship with water content) and external salt concentration on salt partitioning in the polymers with a significant improvement relative to the classic Born model. The updated model most effectively describes NaCl partitioning properties and provides an additional fundamental understanding of salt partitioning processes, for NaCl, KCl, and LiCl, in hydrated polymers that are of interest for a variety of environmental and biological applications.

应用 Born 模型描述水合聚合物中的盐分配


经典的 Born 模型可用于预测在水合聚合物中观察到的盐分配特性，但这些预测与实验数据之间通常存在显着的定量差异。在这里，我们使用更新版本的 Born 模型，重新制定以考虑水合聚合物的局部环境和网格尺寸，来描述模型交联聚乙二醇二丙烯酸酯的先前发布的 NaCl、KCl 和 LiCl 分配特性聚合物。这种重新制定的 Born 模型描述了聚合物结构（即网络网格尺寸及其与水含量的关系）和外部盐浓度对聚合物中盐分配的影响，相对于经典的 Born 模型有显着改进。更新后的模型最有效地描述了 NaCl 分配特性，并提供了对水合聚合物中 NaCl、KCl 和 LiCl 的盐分配过程的额外基本了解，这些聚合物对各种环境和生物应用都很感兴趣。
