General description

Trichloro(1H,1H,2H,2H-perfluorooctyl)silane (PFOCTS) is a chlorosilane that forms a self-assembled monolayer (SAM) on a variety of substrates. It is majorly used to modify the surface with superhydrophobic properties. It is a biocompatible polymer with low surface energy. PFOCTS exhibits anti-fouling properties with high wettability which facilitates the release of different composites from the mold.

Application

PFOCTS is a coupling agent that is used to silanize the substrate for the fabrication of microfluidic devices using soft lithography. It can also be used on silicon base that forms a chemically patterned surface for quantitative analysis of insoluble surfactants in the polymeric matrix. Alumina membranes can be treated with PFOCTS for the formation of surperhydrophobic polyimide (PI) based nanotube arrays.
