詳細

詳細

Ethoxytrimethylsilane (ETMS) is an alkoxysilane that is used as a capping agent, which can tune the hydrophobic properties for a variety of substrates by coupling with the surface hydroxyl groups.

Sodium acetylacetonate reacts with dichloro trimethylsiloxyaluminium to form ethoxytrimethylsilane.{70} Ethoxytrimethylsilane reacts with alkali ions to form Si-O-M (M: alkali metal) linkage, which was investigated in detail by 29Si NMR.1

アプリケーション

ETMS can be used to modify the silica nanoparticles to form a hydrophobic coating with ultra-high molecular weight polyethylene on the surface of the steel. It may be used to methylate silica nanoparticles that form silica nano-capsules for stabilized oil-in water emulsions.
