Semifluorinated Polymers

Fluorinated polymers are important materials for applications in many areas. This article summarizes the development of controlled/living radical polymerization (CRP) of semifluorinated (meth)acrylates, and briefly introduces their reaction mechanisms. While the classical CRP such as atom transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer (RAFT) polymerization and nitroxide-mediated radical polymerization (NMP) have promoted the preparation of semifluorinated polymers with tailor-designed architectures, recent development of photo-CRP has led to unprecedented accuracy and monomer scope. We expect that synthetic advances will facilitate the engineering of advanced fluorinated materials with unique properties.1 Introduction2 Atom Transfer Radical Polymerization3 Reversible Addition-Fragmentation Chain Transfer Polymerization4 Nitroxide-Mediated Radical Polymerization5 Photo-CRP Mediated with Metal Complexes6 Metal-free Photo-CRP7 Conclusion
