Description

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.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.
