Effective sol-gel derived protective coatings to prevent the corrosion of steel in marine environment

摘要

Alkoxysilanes are useful precursors for the development of sol-gel derived coatings and hybrid materials. These coatings are in strong competition to organic paints which are well known and used in many fields of application since several decades. In recent studies sol-gel materials draw increasing interest due to many promising properties. In this study we focus on sol-gel derived coatings that can be used to prevent the corrosion of construction steel. Different single source precursors which have been used include commercially available, e.g. monosilanes like methyltriethoxysilane (MTEOS) as well as aminosilane based bridged compounds.
