Octadecyltrimethoxysilane Chemical Properties,Uses,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.
