Used primarily as a surface modifier in nanotechnology and materials science, this compound imparts strong hydrophobic and oleophobic properties to surfaces. Its fluorinated chain enables the formation of self-assembled monolayers (SAMs) on metals like gold and silver, which are utilized in sensors, microelectronics, and anti-fouling coatings. The thiol group anchors the molecule to the surface, while the fluorocarbon tail reduces surface energy, enhancing chemical resistance and water repellency. It is also employed in the development of advanced lubricants and in modifying nanoparticles for biomedical applications due to its stability and inertness.
