Self-healing coatings have attracted a great deal of interest because of their ability to prevent or control the corrosion process, which is a serious challenge in almost all industries. Despite the fact that there are various methods for the evaluation of self-healing performance in coatings, there are still no standard and established methods for these assessments. A new article reviewed the characterisation methods for evaluating the self-healing behavior in polymeric coatings and highlighted the significant benefits and drawbacks of each method. Accordingly, all the methods assessing self-healing performance and self-healing efficiency in polymeric coatings that have been utilised in the most recent studies are described.
Insights into the mechanisms of self-healing
These methods are classified into visualisation and quantitative methods, and the equations for the determination of self-healing efficiency are introduced and the terms are defined. The review aims to provide a comprehensive overview of the characterisation methods used in evaluating self-healing in polymeric coatings. According to the authors, its objective is to pave the way for the development and industrial application of self-healing coatings by offering insights into the mechanisms of self-healing and identifying quantitative methods for its determination.
