Title of Speech: Multifunctional self-healing protective coatings with improved adhesion properties and corrosion-sensing abilities
Abstract: Self-healing coatings inspired by biological systems possess the ability to repair physical damage or recover functional performance with minimal or no intervention. This talk will introduce several recent examples of multifuctional self-healing coatings prepared for active and smart corrosion protection. The coatings exhibited both intrinsic and extrinsic self-healing abilities thanks to the shape memory properties of the coating matrix and the inhibitors encapsulated in thermoplastic microspheres, respectively. The composition of the wall surface of the microspheres was tailored to improve their compatibility with the coating matrix and the steel substrate. The coating resin was also modified to demonstrate corrosion-sensing abilities based on metallic ion complexation and local pH variation.
