Descrizione generale
Trimethoxy(octadecyl)silane (OTMS) is an alkyl silane that functionalizes a variety of nanoparticle surfaces and facilitates a hydrophobic coating with a high-water contact angle and low surface energy.
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.
Applicazioni
Magnetic nanoparticles (Fe2O3) can be surface modified with OTMS. It forms a sorbent for the magnetic solid-phase extraction (MSPE) of endocrine disruptors (organochlorine pesticides) from milk samples. It may form a corrosion protective coating on AZ31 magnesium alloy that finds potential application in automotive industry. It may also be used to form a composite with fly ash that can be coated to achieve a superhydrophobic and UV-protected cotton fabric.
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.

A series of octadecylsilane-modified silicas were prepared by sol-gel and grafting methods. Carbon contents and octadecyl chain conformations were shown to depend on the preparative route. Grafting engenders a low carbon content and a liquid-like chain conformation, while the sol-gel

This study was designed to determine the effect of varying the chemistry of the interfacial phase on critical composite properties in dental nanocomposite materials. Silica nanoparticles were silanized with varying ratios of 3-methacryloxypropyltrimethoxysilane (MPTMS) and octyltrimethoxysilane (OTMS) while keeping the
