Enhanced Anticorrosive Properties of Silane Functionalized Polybenzoxazine @CeO2 Nanocomposites with Polyurethane Coatings on Mild Steel

Abstract

In this study, the durability of polyurethane adhesives are successfully developed using silane-functionalized polybenzoxazine@CeO2 nanocomposites. The electrochemical measurements were used to investigate the mechanical strength of polybenzoxazine nanocomposite with polyurethane materials. The superior results in the process of passivation film that also controlled the dissolution of metal have been characterized by UV-visible, XRD, SEM/EDX, FT IR, TGA-DTA-DSC, micro hardness, gel absorption and water absorption analyses. The mechanical performance of the coated surface that supported up the electrochemical investigations was enhanced by the incorporation of silane functionalized polybenzoxazine@CeO2 nanocomposites with polyurethane. The use of ployurthane in the TGA process increases the cross-linked density of the coating, resulting in high thermal stability. As a result of their superior anticorrosive property, the proposed polybenzoxazine@CeO2 nanocomposites with polyurethane films offer the openings for the development of unique, state-of-the-art anticorrosive adhesives across a wide range of sectors.
