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

In this study, a specific organosilane molecule (octadecyl-dimethyl(3-trimethoxysilylpropyl)ammonium) is used to form soft-templates that store organic corrosion inhibitors (tolytri-azole), 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, en-dows a prolonged anticorrosion effect.
