Polyelectrolytes are an important class of polymeric materials and are increasingly used in complex industrial formulations. A core use of these materials is in mixtures with surfactants, where a combination of hydrophobic and electrostatic interactions drives unique solution behavior and structure formation. In this review, we apply a molecular level perspective to the broad literature on polyelectrolyte-surfactant complexes, discussing explicitly the hydrophobic and electrostatic interaction contributions to polyelectrolyte surfactant complexes (PESCs), as well as the interplay between the two molecular interaction types. These interactions are sensitive to a variety of solution conditions, such as pH, ionic strength, mixing procedure, charge density, etc. and these parameters can readily be used to control the concentration at which structures form as well as the type of structure in the bulk solution.
聚电解质是一类重要的高分子材料，越来越多地用于复杂的工业配方中。这些材料的一个核心用途是与表面活性剂混合，其中疏水相互作用和静电相互作用的结合驱动了独特的溶液行为和结构形成。在本综述中，我们从分子水平的角度审视了关于聚电解质-表面活性剂复合物的广泛文献，明确讨论了疏水相互作用和静电相互作用对聚电解质-表面活性剂复合物（PESCs）的贡献，以及这两种分子相互作用类型之间的相互作用。这些相互作用对多种溶液条件敏感，如pH值、离子强度、混合程序、电荷密度等，这些参数可很容易地用于控制结构形成的浓度以及本体溶液中结构的类型。
