界面上中性与带电聚合物
摘要
链状高分子（聚合物）因其柔性和内部自由度，在吸附于表面和界面时表现出特征性吸附特性。本综述讨论了中性与带电聚合物在平衡状态下的吸附概念与特征，包括聚合物/表面相互作用类型、溶剂质量、表面特性以及聚合物结构。我们特别关注具有水溶性的带电聚合物（电解质聚合物）。 presented a summary of recent progress in this rapidly evolving field. 由于许多实验研究使用的是较刚性的生物高分子，我们详细讨论了半刚性聚合物以及柔性聚合物的情况。首先�述了中性与带电链在溶液中的行为。随后讨论了单个聚合链的吸附。接着综述了多链体系中的吸附与脱附过程。 presented profiles, changes in surface tension and polymer surface excess. Mean-field and corrections due to fluctuations and lateral correlations are discussed. The force of interaction between two adsorbed layers, which is important in understanding colloidal stability, is characterized. The behavior of grafted polymers is also reviewed, both for neutral and charged polymer brushes.
