Figure 2. (A-C) Variation in ε with frequency for PVDF-based nanocomposites incorporating diverse nanofillers at distinct filler loadings; (D-F) log-log plots of dielectric behavior (ε vs. f_c-f) at 1 kHz (inset), comparing different PVDF nanocomposites across a range of filler contents; the ε of the composite materials with diverse fillers at (G) 5 wt% filler content and (H) 1,000 Hz; (I) comparison of ε_eff for raw MXene and modified fillers; (J) packing distribution and equivalent circuit representation of PVDF nanocomposites filled with MXene@PDA and O-MXene@PDA, respectively. ε: Permittivity; PVDF: polyvinylidene fluoride; f_c: cut-off frequency; MXene: titanium carbide; PDA: polydopamine; O-MXene: oxidized MXene; ε_eff: effective permittivity.
