Descrição geral

Triethoxy(octyl)silane (TEOS) is an alkoxide organosilane with four ethyl ester sidechains. It is used as a self-assembled monolayer and provides a hydrophobic coating with low surface energy. The water contact angle is in the range of 150-170°.

Aplicação

Aluminium alloy can be coated with TEOS and 1H, 1H, 2H, 2H perfluorooctyl trichloro silane (PFOTS) to obtain superhydrophobicity with a high contact angle of 160-170° for vessel hulls and marine systems. It may be used to stabilize the porosity for a colorimetric sensor for immediate color changes, which finds potential application in the detection of toxic gases. It may also be used in the production of hybrid zeolites.
Triethoxy(octyl)silane may be used to prepare several formulations for fabricating low-cost, colorimetric sensor arrays to detect toxic gases.
