AbstractFor the purpose of overcoming the lack of durability problems associated with superhydrophobic surfaces which hitherto has limited their use; we prepared multi-stimuli wettability response coatings using a mixture of fluorocarbon resin and urea-formaldehyde microcapsules filled with fluorosilane via interfacial polymerization process. The microcapsules are of good thermal stability and can be triggered to release their core content on exposure to atmospheric conditions resulting in the increase in the water contact angle from 97 degrees to 151 degrees. The prepared coatings gave good adhesion strength, and also showed an increase in the hydrophobic property after undergoing scratch, solvent and UV accelerated aging test. In addition, they offered good self-healing of the hydrophobic property after an initial loss due to alkaline immersion and oxygen plasma etching. The electrochemical measurements revealed a remarkable impedance recovery and suppression of corrosion activities, suggesting them to be a potential candidate material for corrosion protection.
