Objective:

The objective goal of this project is to synthesize new functionalized perfluoropolyethers (PFPEs) for use in the design of nontoxic, fouling-release coatings for marine vessels.

Approach:

The approach to the design of these fouling -release coatings has been the development of a new class of highly functionalized PFPEs. These PFPEs are synthesized by the fluoro-olefin photo-oxidation method via the photo-oxidative copolymerization of fluoro-olefins with functionalized perfluoroalkylvinylether monomers. Post-polymerization derivatization of the pendent groups of these materials to polymerizable functionalities provides materials; which these materials can yield cross linked coatings. The PFPE segments furnish both flexibility and low-surface-energy properties to the coatings, thus providing minimally adhesive properties to the desired substrates.
