摘　　要：聚偏氟乙烯(PVDF基)含氟聚合物由于其独特的性能受到了广泛的关注。将功能化链段引入PVDF基含氟聚合物可以进一步提升其性能并拓展其应用领域。相较于物理共混法和直接共聚改性法,通过接枝改性法将功能化单体引入含氟聚合物的侧链具有更显著的优势,可便捷、高效地得到组成精确,结构可控的接枝共聚物。本文综述了通过活性自由基聚合(包括ATRP、SET-LRP、有机催化原子转移自由基聚合(O-ATRP)、光诱导Cu(Ⅱ)介导RDRP)和高能射线辐射(γ射线,紫外,电子束)等对PVDF基含氟聚合物功能化接枝改性的方法,并对其发展趋势以及改性聚合物的应用前景进行了展望。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.
