Description:
Octadecyltrimethoxysilane is an organosilicon compound, commonly called OTMS. This colourless liquid is used for preparing hydrophobic coatings and self-assembled monolayers. It is sensitive toward weter, irreversibly degrading to a siloxane polymer. It places a C18H39Si "cap" on oxide surface. The formation of OTMS monolayers is used for converting hydrophilic surfaces to hydrophobic surfaces, e,g. for use in certain areas of nanotechnology and analytical chemistry.
