水合的盐络合物PEC的组成和性质强烈地依赖于它们浸入其中的溶液的盐浓度。这种迷人的和polyelectrolyte特定的行为往往是治疗与扩展的理论开发的单组分的双组分溶液。作为替代方案，PEC对盐的响应（即，小离子）可被视为正Pol（+）和负Pol（-）重复单元与其盐抗衡离子配对之间的竞争。简单的平衡表达式提供了随着加入更多的盐可逆的Pol（+）Pol（-）对断裂的程度。这项工作总结了PEC的位点特异性离子配对的观点。出版社：AIP Publishing
The composition and properties of hydrated polyelectrolyte complexes, PECs, depend strongly on the salt concentration of solutions in which they are immersed. This fascinating and polyelectrolytespecific behavior is often treated with extensions of theory developed for single-component polyelectrolyte solutions. As an alternative, the response of PECs to salt (i.e., small ions) may be treated as a competition between the pairing of positive, Pol(+), and negative, Pol(-), repeat units and their salt counterions. Simple equilibrium expressions provide the degree of reversible Pol(+) Pol(-) pair breaking as more salt is added. This work summarizes the site-specific ion pairing view of PECs.
