Abstract

Metal corrosion is the degradation of a metal due to its reaction with the environment. One of the most effective ways of securing metal surface from corrosion is the use of corrosion inhibitors. Surfactants are an important category of corrosion inhibitors that have intrinsic amphiphilicity. The anticorrosion efficacy of surfactants is closely related to their chemical composition, molecular structure, and adsorption affinity on the metal surface. This review first summarizes the corrosion inhibition mechanism of surfactants and elucidates the influence of charge properties and structural characteristics on their corrosion inhibition efficiency, and then discusses the recent development of novel surfactants for metal anticorrosion application. Next, the synergistic effects of surfactants and other materials for metal anticorrosion are elucidated. We finally discuss the problems and challenges for the development of surfactant corrosion inhibitors and give a perspective in this field, hoping to provide help for future research.

表面活性剂在金属缓蚀中的应用
金属腐蚀是指金属因与环境发生反应而发生降解。确保金属表面免受腐蚀的最有效方法之一就是使用缓蚀剂。表面活性剂是一类重要的缓蚀剂,具有内在的两亲性。表面活性剂的防腐效果与其化学成分、分子结构和在金属表面的吸附亲和力密切相关。本综述首先总结了表面活性剂的缓蚀机理,阐明了电荷性质和结构特征对其缓蚀效率的影响,然后讨论了近年来用于金属防腐的新型表面活性剂的发展情况。接着,阐明了表面活性剂与其他材料在金属防腐方面的协同效应。最后,我们讨论了表面活性剂缓蚀剂开发所面临的问题和挑战,并对该领域进行了展望,希望能为未来的研究提供帮助。

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.
