Mesostructured Silica Nanoparticles with Organic Corrosion Inhibitors to Enhance the Longevity of Anticorrosion Effect

Abstract

Abstract In this study, a specific organosilane molecule (octadecyldimethyl(3-trimethoxysilylpropyl)ammonium) is used to form soft-templates that store organic corrosion inhibitors (tolytriazole), and chemically anchor to silica surface during a sol-gel process. As the anchored soft-templates in the resulting mesostructured silica are not removed, it successfully achieves an environmental-friendly synthetic method and a prolonged storage of tolyriazole. Coating of a copper substrate with the mesostructured silica embedding tolytriazole, therefore, endows a prolonged anticorrosion effect.
