Fluorinated polymers are important materials that are widely used in many areas as taking the advantage of inertness to chemical corrosion,prominent weather resistance,low flammability,and good thermal stability.Poly(vinylidene fluoride)(PVDF)based fluoropolymers is the most common type of commercial fluoropolymer especially used as dielectric materials.However,there are always some shortcomings in practical applications,so it is necessary to modify PVDF-based fluoropolymers for better application.Controlled/living radical polymerization(CRP)and related techniques have become a powerful approach to tailoring the chemical and physical properties of materials and have given rise to great advances in modification of PVDF-based fluoropolymers.
