Development of Self-healing Coatings Based on Microcapsules Filled with Active Agents

June 22, 2018 @ 11:00 am – 12:00 pm
200 College St
Toronto, ON M5T 3A1

In this presentation, an overview of recent advances in self-healing coatings is provided. The talk focuses on the microencapsulation of active compounds used mainly in the polymer coatings. Various preparation methods of microcapsules and their advantages and shortcomings will be discussed. In addition, some recent activities in my research group relate to the preparation of ethyl cellulose (EC), urea-formaldehyde (UF), and polyurethane (PU) microcapsules will be described. Self-healing performance of these microcapsules for enhancing the mechanical properties, barrier performance and corrosion resistance of coatings will be presented.

Mojtaba Mirabedini is a University Professor at the Iran Polymer and Petrochemical Institute (IPPI) and head of Color and Surface Coatings Department.  He is recently invited as a visiting Professor at the Eastern Michigan University. Dr. Mirabedini received his PhD in Corrosion Protection Coatings from the University of Manchester (UMIST) in 2000, working under supervision of late Professor David Scantlebury and Proferssor George Thompson. He specializes in smart polymeric coatings, nanocomposites coatings and adhesives. His current research focuses on developing novel smart functional coatings, self-healing coatings, thread locking adhesives, self-cleaning coatings, and advanced pavement markings. Dr. Mirabedini has been collaborating with Prof. Farnood on the microencapsulation of active materials for smart coating applications since 2010.
