In recent years,fluorinated polymers have attracted much attention because of their excellent properties of high resistance to heat and oxygen,superior weatherability,good chemical inertness,low dielectric constants,and low surface energy,and broad application prospect in fields of hydrophobic materials,antifouling materials,surfactant,and contrast agent. Fluorinated copolymers of various topologies have been synthesized and applied in related fields. In this paper,firstly,the properties and current research status of fluorinated polymers are briefly introduced. Secondly,the new research progress of well-defined fluorinated copolymers synthesized by reversible addition-fragmentation chain transfer polymerization(RAFT),atom transfer radical polymerization(ATRP),iodine transfer radical polymerization(ITP),reverse iodine transfer polymerization(RITP),single electron transfer living radical polymerization(SET-LRP),nitroxide-mediated radical polymerization(NMP),and living anionic polymerization(LAP)are reviewed in detail respectively. In addition,the mechanism,advantage and disadvantage of polymerization,and the properties and applications of the fluorinated copolymer obtained are also summarized. Finally,the research foreground and practical application of the design and synthesis of well-defined fluorinated copolymers based on controlled/"living" polymerization are prospected. We put forward that environmentally friendly functional fluorinated polymers will be the research focuses in the future.
