Self-Healing Coatings Based on Stimuli-Responsive Release of Corrosion Inhibitors: A Review

Blog Article

Corrosion inhibitors loaded in coatings promote the protection performance of coatings, avoid the local corrosion of metal substrates, and endow the Web Incense self-healing properties of the coatings.The stimuli-responsive release of corrosion inhibitors, which is generally achieved by loading corrosion inhibitors in containers, is key to the self-healing and long-term protection of the coatings.The loading and release methods of corrosion inhibitors are discussed in the article.First, two kinds of loading methods for corrosion inhibitors are reviewed, which are one-step synthetic methods and multistep synthetic methods.Then the Sleeves released methods of corrosion inhibitors, which can be achieved by intrinsic properties and surface modification of containers, are summarized.
