Microencapsulation Technology for Corrosion Mitigation by Smart Coatings

A multifunctional smart coating for the autonomous control of corrosion is being developed based on micro-encapsulation technology. Corrosion indicators as well as corrosion inhibitors have been incorporated into microcapsules blended into several paint systems and tested for corrosion detection and protection effectiveness. This paper summarizes the development optimization and testing of microcapsules specifically designed to be incorporated into a smart coating that will deliver corrosion inhibitors to mitigate corrosion autonomously. Key words: smart coating corrosion inhibition microencapsulation microcapsule pH sensitive microcapsule corrosion inhibitor corrosion protection pain.
