Fluorinated Oligomers and Polymers in Photopolymerization
Résumé
After an introduction reporting the properties and the applications of fluoropolymers and photopolymerizable derivatives, several basic information on photopolymerization processes are proposed. Then, this review deals with the state of the art on the synthesis of photopolymerizable fluoromonomers and oligomers: most classes of monomers are treated in separate sections (except fluorinated allyl ethers, which are used in copolymerization and are mentioned with the fluoro(meth)acrylics and macromonomers), eventually dividing the descriptions according to the monomer functionality. A short section further is devoted to fluorinated photoinitiators. After the synthesis, this review describes the main issues of the photopolymerization of fluorinated monomers together with the properties and performances obtained. A focus is given on the telechelic monomers and oligomers to insure a suitable crosslinking and on the copolymerization of fluorinated monomers for the surface modification of the obtained materials. Finally, properties and relevant applications (such as coatings and adhesives, optical fibers and flexible displays, polymer Exchange Membrane for Fuel Cell, microfluidic devices, high performance elastomers, and replica moldings) of these fluorinated photopolymerized materials will illustrate this review.
