Description

Description générale

Octadecylsilane is an organosilicon compound that consists of a long-chain hydrocarbon (18 carbons) bonded to a silicon atom through a carbon-silicon bond. It is widely used in various applications due to its high surface activity, making it an excellent adsorbent for non-polar organic compounds. It is also used as a surface modifier or coating agent.

Application

Octadecylsilane can be used as a modifying agent for montmorillonite clay nanoparticles, which are used as a filler material in the synthesis of poly(methyl methacrylate) (PMMA)/silylated montmorillonite composites.
