Abstract

Over the last two decades, a significant body of research has been developed trying to understand the association and properties of mixtures formed by oppositely charged polyelectrolytes and surfactants. Particular emphasis has been given to their interfacial properties and the intriguing formation of nonequilibrium states. The synergy between these components at interfaces has attracted considerable attention due to its relevance in various industrial and biological applications. The combination of oppositely charged entities leads to complex interactions that influence the stability and behavior of interfaces. This review critically examines recent advances toward understanding the interfacial behavior when polyelectrolytes and surfactants coexist. Emphasis is placed on the existence of nonequilibrium states, shedding light on transient phenomena and kinetic aspects that play a crucial role in the overall system behavior. This will provide insights into the mechanisms governing the interfacial phenomena in these mixed systems. In summary, this review will contribute to the fundamental understanding of colloidal and interfacial science, offering a valuable perspective on designing and optimizing materials with tailored properties.

流体界面上聚电解质-表面活性剂体系的非平衡状态:重要综述
在过去的二十年里,人们已经开展了大量研究,试图了解由带电相反的聚电解质和表面活性剂形成的混合物的关联和特性。研究重点尤其放在它们的界面特性和非平衡态的形成上。这些成分在界面上的协同作用因其在各种工业和生物应用中的相关性而备受关注。带相反电荷的实体结合在一起会产生复杂的相互作用,从而影响界面的稳定性和行为。本综述认真研究了了解聚电解质和表面活性剂共存时界面行为的最新进展。重点关注非平衡态的存在,揭示在整个系统行为中起关键作用的瞬态现象和动力学方面。这将有助于深入了解这些混合体系中界面现象的作用机制。总之,这篇综述将有助于从根本上理解胶体和界面科学,为设计和优化具有定制特性的材料提供宝贵的视角。

期刊介绍: Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
