钢铁表面自组装缓蚀膜

Inhibitive Self-assembled Monolayers on Steel

分子自组装技术在表面工程、纳米技术、膜技术和生命科学领域已有很广泛的应用,对未来材料发展起到很重要的作用,已成为近年来科研工作者关注的重点之一。钢铁作为广泛应用的工程材料,因其容易被腐蚀的特点,缓蚀膜的研究关系重大。钢铁表面自组装分子膜不仅具有分子取向性好、排列紧密有序、热力学稳定、用量少、成本低等优点,而且缓蚀效果十分优良。因此,钢铁表面自组装缓蚀膜技术目前引起了众多学者的关注。本文综述了钢铁表面自组装缓蚀膜的主要体系、影响因素及其表征技术三个方面的最新研究进展,并对自组装膜的发展方向进行了展望。

Self-assembly method is widely used in surface engineering,nanotechnology,membrane technology and bioscience,and it is play an important role in future materials＇ development.Self-assembly technology has become the focus of research in recent years.As a widely used engineering materials,the research of steel inhibitive self-assembled monolayers（SAMs） is important.The SAMs on steel not only has good orientation,closely ordered,thermodynamic stability and low cost,but also has high corrosion inhibition efficiency.Therefore,the inhibitive self-assembled monolayers on steel attracts many researchers＇ attentions.This paper reviewed three aspects of the latest research progress including the main self-assembly systems,the influenced factors and characterization technique on steel,and then development of the self-assembled monolayers is prospected.
