Product Introduction:

1H,1H,2H,2H-Perfluorodecanethiol, often abbreviated as PFDT, is a highly specialized organosulfur compound. It consists of a long perfluorinated alkyl chain (C8F17C2H4-) terminated with a reactive thiol (-SH) group.

It typically appears as a white to off-white crystalline solid. This compound is extremely valuable for creating highly functionalized surfaces due to its unique dual functionality: the long perfluorinated tail provides exceptional hydrophobicity, oleophobicity, and low surface energy, while the terminal thiol group exhibits a strong and selective affinity for noble metal surfaces, particularly gold.

Main Uses:

1. Self-Assembled Monolayers (SAMs) on Gold: PFDT is one of the most widely used molecules for forming highly ordered and robust self-assembled monolayers (SAMs) on gold surfaces. The thiol group chemically bonds to gold, while the fluorinated chains pack tightly, creating a dense, highly repellent surface. These SAMs are critical in microelectronics, biosensors, and fundamental surface science research.

2. Hydrophobic and Oleophobic Coatings: It is extensively used to create highly water-repellent (hydrophobic) and oil-repellent (oleophobic) coatings on various substrates, especially those amenable to thiol-metal interactions or where it can be incorporated into polymeric systems. These coatings enhance anti-fouling, anti-corrosion, and self-cleaning properties.

3. Microelectronics and Nanotechnology: In microfabrication and nanofabrication, PFDT SAMs are used for patterning, creating protective layers, controlling wettability, and engineering surface properties of electronic components and nanoscale devices.

4. Biosensors and Biomedical Devices: The ability to create tailored, bio-inert, or bio-repellent surfaces makes PFDT useful in the development of biosensors, lab-on-a-chip devices, and medical implants to control protein adsorption and cell adhesion.

5. Corrosion Protection: Fluorinated thiol SAMs can provide excellent long-term corrosion protection for metal surfaces due to their dense packing and chemical inertness.
