Description

General description

Reaction between dodecene and triethoxysilane yields dodecyltriethoxysilane. 1

Dodecyltriethoxysilane (DTES) is an organosilane, which is used as a coupling agent. It forms alkylsiloxane based films that can be used to tune the wettability and facilitate a variety of surfaces with hydrophobicity.

Application

A study reports the use of dodecyltriethoxysilane to form a silica nanofluid which alters the water contact angle of an oil-wet carbonate substrate. {68}

Dodecyltriethoxysilane can be used in the surface treatment of calcite crystals for the determination of the effect of wettability with the incorporation of nanoparticles. It may be electrodeposited with tetraethoxysilane, which can be used as an anti-corrosive coating on mild steel.
