In this work, nanocomposites (poly(vinylidenefluoride–trifluoroethylene–chlorotrifluoroethylene)/Graphene nanosheets) (P(VDF–TrFE–CTFE)/GNS) were fabricated via solution cast process. GNS were covalently functionalized with KH550 to improve their interfacial interactions with the terpolymer matrix P(VDF–TrFE–CTFE). Compared to neat terpolymer, significantly improved dielectric permittivity and low loss were observed for the composites. For instance, at 1 kHz the P(VDF–TrFE–CTFE)/GNS composites with 4% GNS possessed a dielectric permittivity of 144, over 14 times larger than that of neat terpolymer, while the loss was only 0.56. These findings represent an effective route to design potential dielectric polymer films for high-charge storage capacitors.
