“…According to the synthetic approach, the fluorination of common polymers can be divided into (i) copolymerization with fluorinated monomers, , (ii) direct functionalization using fluorination agents such as F 2 and HF, − and (iii) introduction of fluorinated functional moieties. , Copolymerization is a very general method of introducing fluoro-functionalities into polymers owing to its ease of implementation and cost-effectiveness; , however, the scope of fluorinated monomers is restricted by the need to carefully consider the polymerization conditions and the level of synthetic difficulty. , On the other hand, direct fluorination is applicable to most organic compounds but involves the use of reagents posing acute toxicity and environmental problems, − e.g., F 2 , , HF, , and BF 3 . In contrast, the introduction of fluorinated moieties offers the advantages of mild reaction conditions, applicability to a wide range of polymers, and control over functionality (or selective functionalization) in the case when the polymer has certain reaction sites. ,,, However, this technique still suffers from drawbacks due to the complex synthesis of fluorination agents and the limited scope of fluorinated moieties …”
