(a) The dielectric constant and dielectric loss (tan δ) as a function of frequency at room temperature for f-DOPA@TiO2 NWs/P(VDF-HFP) nanocomposites. (b) Temperature-dependent dielectric spectra of f-DOPA@TiO2 NWs/P(VDF-HFP) nanocomposites. (c) Frequency dependent of imaginary electric modulus at various temperature of P(VDF-HFP)-based nanocomposites with 15 vol % of f-DOPA@TiO2 NWs.
