(a) D-E loops under unipolar electric fields of 100 Hz for f-DOPA@TiO2 NWs/P(VDF-HFP) nanocomposites with different filler concentrations. (b) The discharged energy densities and charge-discharge efficiency of P(VDF-HFP)-based nanocomposites with different volume fractions of f-DOPA@TiO2 NWs under varied applied fields. (c) Discharged energy densities of 2.5 vol % f-DOPA@TiO2 NWs/P(VDF-HFP) and other nano-TiO2 related polymer nanocomposites reported in previous literatures in the range of 220 MV m−1 to 530 MV m−1. (d) Breakdown strength of the P(VDF-HFP)-based nanocomposites at varied volume fractions of f-DOPA@TiO2 NWs. (e) Leakage current density of f-DOPA@TiO2 NWs/P(VDF-HFP) nanocomposites with different filler concentrations at varied applied electric field. (f) Electrical resistivity of P(VDF-HFP)-based nanocomposites with different volume fractions of f-DOPA@TiO2 NWs under an electric field of 100 MV m−1.
