To address the challenge of metal contamination, a “graft from” approach via organocatalyzed atom transfer radical polymerization (O-ATRP) is developed to synthesize poly(vinylidene fluoride-co-chlorotrifluoroethylene) (P(VDF-co-CTFE)) graft copolymers. N-phenylphenothiazine is utilized as a model organic photoredox catalyst for catalyzing the (co)polymerization of methyl methacrylate (MMA), methacrylate (MA), and n-butyl acrylate (BA). By employing this technique, high temporal control of polymerization and graft content are achieved. A series of P(VDF-co-CTFE)-g-PMMA, P(VDF-co-CTFE)-g-PMA, and P(VDF-co-CTFE)-g-PBA is prepared under mild conditions. The resultant graft copolymer can be used as macroinitiator to re-initiate O-ATRP to synthesize P(VDF-co-CTFE)-g-(PMMA-b-PMA), which might exhibit the potential application as novel dielectric material. A “Graft from” approach via organocatalyzed atom transfer radical polymerization is developed to synthesize poly(vinylidene fluoride-co-chlorotrifluoroethylene) graft copolymers by using N-phenylphenothiazine as a model organic photoredox catalyst. Great temporal control of polymerization and high graft content are achieved and the resultant graft copolymers might be used as novel dielectric materials.
