78560-44-8 Usage
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
Different sources of media describe the Application of 78560-44-8 differently. You can refer to the following data:
1. 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.
2. 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.

Check Digit Verification of cas no
The CAS Registry Mumber 78560-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,6 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78560-44:
(7*7)+(6*8)+(5*5)+(4*6)+(3*0)+(2*4)+(1*4)=158
158 % 10 = 8
So 78560-44-8 is a valid CAS Registry Number.

Perfluoroalkyltrialkoxysilanes were prepared by hydrosilylation of the allylic or vinylic derivatives with trialkoxysilane or with trichlorosilane (followed by a quantitative methanolysis). The hydrolysis and polycondensation of these precursors were performed in the presence of tetrabutylammoniumfluoride (TBAF) as the catalyst, leading to a series of new polysilsesquioxanes, which were characterized by solid state 13C and 29Si CPMAS NMR. The porosity and surface area of these materials were determined by N2 absorption experiments. Thermogravimetric analyses (TGA) were also performed. The surface properties of films prepared from these silsesquioxanes were studied by contact angle measurements. The hybrids having fluoroalkyl groups at the surface of the material showed a better thermostability and a higher hydrophobic and oleophobic character than their hydrocarbon analogues.
