General description

Trimethoxy(octyl)silane is an organosilane. The effect of hydrolyzed silane on the penetration of water into a lamellar liquid crystal was studied.
Trimethoxy(octyl)silane (TMOS) is an organosilane that is used as a coupling and surface modifying agent to enhance the water contact angle and lower the surface energy.

Application

Trimethoxy(octyl)silane was used for the silanization of silica nanoparticles. Surface modification of hydrophobic (T805) titania particles with the silane was reported.
Trimethoxy(octyl)silane (TMOS) is used to functionalize the surface of silica to promote the adhesion with gold nanoparticles (AuNPs) for use in the fabrication of acrylate nanocomposite based photonic devices. It can be coated on silica fiber based epoxy to improve the hydrophobic characteristics and to protect the surface from corrosion.
