Smart coatings protect metals from corrosion by providing a self-repairing system that detects and responds to electrochemical processes responsible for corrosion. When corrosion events are sensed, the coating releases corrosion inhibitors to shut down the corrosion process.  This presentation will describe smart coating system strategies employing polyaniline, an electroactive polymer (EAP), for the corrosion protection of high tensile strength aluminum alloys important to the aerospace industry. These coating systems capitalize on two unique properties that EAPs possess, i.e. their ability to (1) conduct electricity and (2) bind and expel molecules or ions in response to an electrochemical potential. Our approach is to incorporate molecules as EAP dopants which when released inhibit oxygen reduction reactions responsible for pitting corrosion. Proposed mechanisms, progress in selecting inhibitors, and ASTM B117 salt fog results will be presented.
