1H,1H,2H,2H-Perfluorodecyltrichlorosilane Chemical Properties,Usage,Production

Physicochemical Properties

1H,1H,2H,2H-Perfluorodecyltrichlorosilane, also known as FDTS, is a colorless liquid chemical with molecular formula C10H4Cl3F17Si. FDTS molecules form self-assembled monolayers. They bond onto surfaces terminated with hydroxyl (-OH) groups, such as glass, ceramics, or SiO2 forming a regular covalent bond. It anchors on oxide surfaces with its tricholoro-silane group and attaches covalently.

Application

1H,1H,2H,2H-Perfluorodecyltrichlorosilane (FDTS) monolayer is often applied to movable microparts of microelectromechanical systems (MEMS). FDTS monolayer reduces surface energy and prevents sticking, so they are used to coat micro- and nano-features on stamps for a nanoimprint lithography which is becoming a method of choice for making electronics, organic photodiodes, microfluidics and other. Reduced surface energy is helpful for reduction of ejection force and demolding of polymer parts in an injection molding and 1H,1H,2H,2H-Perfluorodecyltrichlorosilane (FDTS) coating was applied onto some metallic injection molding molds and inserts. Further, it is used to coat micro-nano features on stamps for a nano imprint lithography. In addition, it is used in the preparation of other products by reacting with methanol.

Chemical Properties

colourless to straw-coloured liquid with an odour of hydrogen chloride

Uses

1H,1H,2H,2H-Perfluorodecyltrichlorosilane (CAS# 78560-44-8) is a useful compound used as part of antireflective coatings for solar cell efficiency improvement. The high level of hydrophobicity of 1H,1H,2H,2H-Perfluorodecyltrichlorosilane also makes it useful as coating for electrical insulators.

Application

DTS(FBTTh2)2 can be used as a conjugating polymer that forms a donor-acceptor system with acceptor molecules such as perylene diimide, PC71BM and other fullerenes for the fabrication of bulk-heterojunction based solar cells.
A tri-functional fluoro-carbon terminated silane (1H,1H,2H,2Hperfluorodecyltrichlorosilane, PFTCS) was used in solutions of hexane to create surfaces with teflon-like properties.

General Description

DTS(FBTTh₂)₂ is a conductive polymer that can be used as a donor molecule. It has a narrow band gap and shows a maximum power conversion efficiency of 7.0%. Its photostability is more than that of P3HT.

Advantages

As a hydrophobic coating, 1H,1H,2H,2H-Perfluorodecyltrichlorosilane (FDTS) to all surfaces having access to organic coating solutions could minimize release stiction. Replacement of the organic fluids with water produces a condition in which the fluid no longer wets machine components, minimizing capillary forces below the level needed to pull compliant structures into contact. Both octadecyltrichlorosilane and FDTS have the added benefits of reducing in-use stiction, friction, and wear, with FDTS exhibiting lower adhesion. This compound also could be used to establish a facile construction of transparent and amphiphobic coatings. The fluoroalkyl silane groups were grafted onto the ChNFs coating surface after the PFDTS deposition. The prepared transparent and amphiphobic coatings are promising in anti-fingerprint protection for optical lenses/sensors and display screens[1-2].
