接枝改性PVDF基含氟聚合物

Poly(vinylidene fluoride)(PVDF)-based fluoropolymers have received widespread attention due to their unique properties. Poly(vinylidene fluoride)(PVDF)-based fluoropolymers have received widespread attention due to their unique properties. Incorporation of functional segments on PVDF-based fluoropolymers has been an important way to improve their performance and expand the application areas. Compared with the physical blending and the direct copolymerization approaches, significant advantages have been witnessed by employing the graft modification method, which provides an easy and efficient way to obtain well-defined fluoro-copolymer with precise compositions. This review highlights the methods of functional graft modification of PVDF-based fluoropolymers via living radical polymerization (including atom transfer radical polymerization (ATRP), single electron transfer-living radical polymerization (SET-LRP), organocatalyzed atom transfer radical polymerization (O-ATRP), photo-induced Cu(Ⅱ)-mediated reversible deactivation radical polymerization (RDRP) and high energy ray radiation (γ-ray, ultraviolet, electron beam)). The opportunities and applications are proposed for the further development.
