Octadecyltrimethoxysilane Chemical Properties,Usage,Production

Chemical Properties

Colorless transparent liquid

Uses

OTS is used for the development of self assembled monolayers(SAMs). OTS is also used to modify the silica dielectric surface in organic field effect transistors.

Uses

For preparing hydrophobic coatings and self-assembled monolayers.

General Description

Trimethoxy(octadecyl)silane (OTS) is an important alkylsilane that can form strong covalent bonds with silicon oxide and serves as a potential lubricant for micro electro mechanical systems (MEMS). OTS is largely used for surface chemical modification, modifying silica resulted in an increased charge carrier mobility for a variety of vacuum deposited and solution cast organic semiconductors.
