Abstract

Layered double hydroxides (LDHs) are recognized as a promising material for the prevention of corrosion in metals and their alloys due to their unique structure, composition, controllability and anion exchange properties. However, traditional LDHs can only serve as a physical barrier for short-term protection. To provide additional intelligent self-healing functions, LDHs loaded with corrosion inhibitors have been developed to enhance the protective ability of the coating and improve the durability of the metal matrix. Despite this progress, there is currently a lack of a complete review summarizing the status of different types of LDHs nanocontainers and control of corrosion inhibitor release behavior. This paper reviews recent advancements in metal corrosion protection using LDHs loaded with corrosion inhibitors, including the preparation process and anti-corrosion mechanism of LDHs loaded with corrosion inhibitors. Additionally, factors affecting the release behavior of corrosion inhibitors are analyzed, and existing problems and future development trends are proposed and discussed.

层状双氢氧化物抑制剂纳米容器的活性腐蚀保护：综述

层状双氢氧化物（LDHs）由于其独特的结构、组成、可控性和阴离子交换性能而被认为是一种很有前途的金属及其合金防腐材料。然而，传统的ldh只能作为短期保护的物理屏障。为了提供额外的智能自修复功能，人们开发了装载缓蚀剂的LDHs，以增强涂层的保护能力，提高金属基体的耐久性。尽管取得了这些进展，但目前还缺乏对不同类型的LDHs纳米容器的现状和缓蚀剂释放行为控制的完整综述。本文综述了近年来载缓蚀剂低分子量聚合物在金属防腐方面的研究进展，包括载缓蚀剂低分子量聚合物的制备工艺和防腐机理。分析了影响缓蚀剂释放行为的因素，提出并讨论了缓蚀剂存在的问题和未来的发展趋势。
