Product Introduction:

1H,1H,2H,2H-Perfluorooctyltrichlorosilane, often abbreviated as FOTS, is a highly specialized organosilane compound. It features a long perfluorinated alkyl chain (C6F13C2H4-) attached to a trichlorosilane group (-SiCl3). It typically appears as a colorless to pale yellow clear liquid.

This compound is extremely valuable for surface modification due to its unique dual functionality: the perfluorinated tail provides exceptional hydrophobicity, oleophobicity, and low surface energy, while the trichlorosilane head group readily reacts with hydroxyl groups on various substrates (e.g., glass, silicon, metal oxides) to form robust covalent bonds.

Main Uses:

1. Hydrophobic and Oleophobic Coatings: FOTS is extensively used to create highly water-repellent (hydrophobic) and oil-repellent (oleophobic) coatings on a wide range of surfaces. These coatings are applied to glass, ceramics, metals, textiles, and electronics to prevent wetting, reduce friction, and enhance anti-fouling properties.

2. Surface Modification for Microfabrication: In the semiconductor and microelectronics industries, FOTS is crucial for modifying surfaces of silicon wafers, photomasks, and microfluidic devices. It helps in creating low-friction surfaces, anti-stiction layers, and controlling wettability for precise patterning and device performance.

3. Self-Assembled Monolayers (SAMs): It is a common precursor for forming stable, well-ordered self-assembled monolayers (SAMs) on various substrates. These SAMs are fundamental in nanotechnology, molecular electronics, biosensors, and anti-corrosion applications.

4. Anti-Corrosion and Anti-Fouling: By forming a protective, low-surface-energy layer, FOTS coatings can significantly improve the corrosion resistance of metals and reduce the adhesion of biological or environmental fouling agents on various surfaces.

5. Optoelectronics and Displays: It can be used to modify optical surfaces to reduce glare, improve clarity, or create anti-fingerprint coatings on screens for electronic devices.
