Sol–Gel Synthesis of SiO2 Containers Using Micelles of an Anionic Corrosion Inhibitor as a Template and the Prospects of Creation Protective Coatings Based on Them

Abstract

It has been shown that silica container particles can be loaded with large amounts of an anionic corrosion inhibitor, sodium N-oleyl sarcosinate, at the stage of the sol−gel synthesis of the particles by using its micelles as a template. When incorporated into paint and varnish coatings, such containers efficiently protect low-carbon steel and D16 aluminum alloy from corrosion under severe conditions of neutral salt spray.
