Abstract

Organic coatings sustain damage during service inevitably. Accurately locating the damaged site and healing it simultaneously to prevent substrate exposure are significant challenges in extending the service life of metallic structures. This study reports on a smart protective coating with self-reporting and self-healing capabilities. The strategy was realized by embedding polyacrylonitrile (PAN) core-shell nanofibers containing 2-amino-1,3,4-thiadiazole (2-AT) and crystal violet lactone (CVL) into organic coatings. When the PAN@2-AT/CVL coating was damaged, CVL at the damaged site emitted bright blue fluorescence under UV light, while 2-AT could adsorb and form a thin film on the steel surface to inhibit corrosion. Furthermore, the flexibility of the PAN@2-AT/CVL coating was significantly enhanced compared to the blank coating, which helped to reduce the formation of microcracks in the coating. The smart coating was expected to be widely applied for the protection of infrastructure in marine environments, offering new solutions for improving the performance of metallic protection materials.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
