Used primarily as a surface modification agent to create highly hydrophobic and oleophobic coatings. It forms self-assembled monolayers on metal surfaces, especially gold, silver, and copper, providing exceptional water and oil repellency. Commonly applied in microelectronics for protecting sensitive components from moisture and corrosion. Also utilized in lab-on-a-chip devices and microfluidics to control wetting behavior and reduce surface adhesion. Its long perfluorinated chain offers thermal and chemical stability, making it suitable for harsh environments. Employed in research settings to study surface phenomena and molecular interactions at interfaces.
