Used in the synthesis of fluorinated polymers that exhibit excellent water and oil repellency, making them ideal for coatings in textiles, paper, and electronic materials. Its fluorinated side chain enhances chemical resistance and thermal stability in specialty coatings. Commonly employed in surface treatment agents and as a monomer in copolymers for low-surface-energy applications. Also utilized in optical materials due to its transparency and refractive index properties. Shows promise in medical device coatings for improved biocompatibility and antimicrobial surfaces.
