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.

We conducted a combined experimental and numerical study of the spreading of insoluble surfactants on spatially confined thin liquid films. We found that the spreading dynamics can locally be represented by a power-law relation x∼t(α). We determine the time evolution...
