The understanding of the deposition of oppositely charged polyelectrolytes-surfactant mixtures onto solid surfaces presents a high interest in current days due to the recognized impact of the obtained layers on different industrial sectors and the performance of several consumer products (e.g. formulations of shampoos and hair conditioners). This results from the broad range of structures and properties that can present the mixed layers, which in most of the cases mirror the association process occurring between the polyelectrolyte chains and the oppositely charged surfactants in the bulk. Therefore, the understanding of the adsorption processes and characteristics of the adsorbed layers can be only attained from a careful examination of the self-assembly processes occurring in the solution. This review aims to contribute to the understanding of the interaction of polyelectrolyte-surfactant mixtures with solid surfaces, which is probably one of the most underexplored aspects of these type of systems. For this purpose, a comprehensive discussion on the correlations between the aggregates formed in the solutions and the deposition of the obtained complexes upon such association onto solid surfaces will be presented. This makes it necessary to take a closer look to the most important forces driving such processes.

由于获得的层对不同工业领域的公认影响以及几种消费产品的性能（例如洗发水和护发素配方）的影响，对带相反电荷的聚电解质-表面活性剂混合物在固体表面上沉积的理解引起了当今的高度关注。 ）。这是由于可以提供混合层的广泛的结构和性能导致的，在大多数情况下，这些现象反映了聚电解质链与本体中带相反电荷的表面活性剂之间发生的缔合过程。因此，仅通过仔细检查溶液中发生的自组装过程才能获得对吸附过程和被吸附层特性的理解。这篇综述旨在促进对聚电解质-表面活性剂混合物与固体表面相互作用的理解，这可能是这类系统中最未得到充分研究的方面之一。为此目的，将对溶液中形成的聚集体与所得复合物在固体表面上缔合后的沉积物之间的相关性进行全面讨论。这使得有必要仔细研究驱动此类过程的最重要因素。将对溶液中形成的聚集体与所得配合物在固体表面上缔合后的沉积物之间的相关性进行全面讨论。这使得有必要仔细研究驱动此类过程的最重要因素。将对溶液中形成的聚集体与所得配合物在固体表面上缔合后的沉积物之间的相关性进行全面讨论。这使得有必要仔细研究驱动此类过程的最重要因素。
