Abstract
The octaaminopropyl polyhedral oligomeric silsesquioxane (OapPOSS) was firstly synthesized through hydrolytic condensation of 3-aminopropyltriethoxysilane. Then, the secondary amine containing POSS was prepared by Michael addition reaction of OapPOSS and diethyl maleate. The resulting hybrid nanomaterial is a viscous liquid that can be uniformly dispersed in the epoxy resin as a reactive component. Results of electrochemical impedance spectroscopy indicated that functionalized POSS significantly enhanced the anticorrosion performance of epoxy coatings. The POSS, acts as a cross-linkage, improved the crosslink density of resin matrix and enhanced the impermeability of composite coatings.
