To address this issue, self\u2010healing coatings, which are intrinsically able to recover from damages upon exposure to external stimuli, are currently gaining increasing attention. Herein, waterborne polyurethanes (PU) are synthesized, and a Diels\u2013Alder adduct is added into the polymeric backbone to endow the material with self\u2010healing functionality. The effect of different diisocyanate in PU synthesis is explored, namely isophorone diisocyanate, 4,4\u2032\u2010dicyclohexylmethane diisocyanate (HMDI), and hexamethylene diisocyanate. The obtained results highlight the key role of the interactions among soft and hard segments in ultimately defining the coating performances. Actually, the combination of Fourier transform infrared spectroscopy, atomic force microscopy and X\u2010ray diffration analysis reveals that the HMDI\u2010based PU have showed the best balance in terms of H\u2010bonding strength among hard segments and crystallinity degree in the soft ones. This allows to reach a good compromise in terms of mechanical resistance, anticorrosion properties, and self\u2010healing ability.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.1002\/admi.202100117<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Changjiang Yu, Martina Salzano de Luna, Andrea Russo, Ignazio Adamiano, Fabio Scherillo, Zhanhua Wang, Xi Zhang, Hesheng Xia, Marino Lavorgna<\/div>\n<h4>Abstract:<\/h4>\n<div class=\"b-intro\">Abstract Organic coatings are extensively investigated as possible solution to prevent or at least retard the occurring of corrosion processes on metal surfaces.
