The application of mesoporous silica nanoparticles (MSN) as smart containers to distribute corrosion inhibitors gradually over time for metal protection has been well documented. This material possesses unique properties such as tunable surface and pore, high thermal and chemical stability, large pore volume and pore size, relatively low toxicity, and water solubility. Improving the service life of coatingsThese properties of MSN enable it to encapsulate large volumes of corrosion inhibitors which upon installation of an appropriate gatekeeper can release inhibitors at a controlled rate thereby improving the service life of coatings when dispersed within. Reading tip: Corrosion protection coatingsThe book “Anticorrosive Coatings: Fundamentals and New Concepts” brings together all the disciplines involved in the creation and use of corrosion protection coatings for metals. It presents the latest insights into the quality and chemistry of surfaces, the proper way to prepare them by conversion treatment, the function of resins and anticorrosion pigments in paints, and novel concepts in corrosion protection.
