| | Octadecyltrimethoxysilane Usage And Synthesis |
| Chemical Properties | Colorless transparent liquid | | Uses | For preparing hydrophobic coatings and self-assembled monolayers. | | 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. | | 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. |
