Abstract
In this article, we represent preparation of renewable source based smart polyurethane coatings reacting polyols prepared by acetylation of neem oil with different diisocyanates in presence of encapsulated corrosion inhibitor. The structures of polyols were confirmed by Fburier transfer infra-red and nuclear magnetic resonance spectroscopic techniques. The prepared polyols were used to form polyurethane coatings by treating with diisocyanates such as methylene phenyl, dicyclohexylmethane, and isophorone diisocyanates. Further, conversion of polyurethane to smart coatings was carried by incorporation of encapsulated form of quinoline as a corrosion inhibitor. Coatings were characterized for their thermal stability and physico-chemical properties by suitable sophisticated techniques. Anticorrosive properties of the smart coatings were studied by exposing them to,corrosive medias like 0.5 M HCl and 3.5% NaCl solutions. Incorporation of encapsulated corrosion inhibitor into the neem oil based smart PU coatings shown enhanced anticorrosive property. Finding of this study also shown encapsulated form of commercial corrosion inhibitor can be extended for other PU coatings. (C) 2015 Elsevier B.V. All rights reserved.
