The current understanding of interactions between surfaces coated with polyelectrolytes is reviewed. Experimental data obtained with various surface force techniques are reported and compared with theoretical predictions. The majority of the studies concerned with interactions between polyelectrolyte-coated surfaces deal with polyelectrolytes adsorbed to oppositely charged surfaces, and this is also the main focus of this review. However, we also consider polyelectrolytes adsorbed to uncharged surfaces and to similarly charged surfaces, areas where theoretical predictions are available, but relevant experimental data are mostly lacking. We also devote sections to interactions between polyelectrolyte brush-layers and to interactions due to non-adsorbing polyelectrolytes. Here, a sufficient amount of both theoretical and experimental studies are reported to allow us to comment on the agreement between theory and experiments. A topic of particular interest is the presence of trapped non-equilibrium states that often is encountered in experiments, but difficult to treat theoretically.
本文综述了目前对聚电解质涂层表面间相互作用的理解。报告了用各种表面力技术获得的实验数据，并与理论预测进行了比较。大多数关于聚电解质涂层表面间相互作用的研究涉及吸附在带相反电荷表面上的聚电解质，这也是本综述的主要重点。然而，我们也考虑了吸附在不带电表面和带相同电荷表面上的聚电解质，在这些领域有理论预测，但大多缺乏相关实验数据。我们还专门讨论了聚电解质刷层之间的相互作用以及非吸附性聚电解质引起的相互作用。在此，报告了足够数量的理论和实验研究，使我们能够对理论与实验之间的一致性进行评论。一个特别有趣的话题是实验中经常遇到但理论上难以处理的被困非平衡态的存在。
