The introduction of montmorillonite filler into polymer/conductor composites can effectively reduce dielectric loss and conductivity of the composites. The novel ternary composites, with the addition of montmorillonite, show a mildly reduced dielectric constant, but significantly decreased dielectric loss and conductivity.
Dielectric constants of polymer/conductor composites are often high, owing to strong interface interaction in those composites. They can be used for dielectric energy storage, but they usually have high dielectric loss and conductivity. In order to reduce the dielectric loss and conductivity in poly(vinylidene fluoride-hexafluoropropylene) (P(VDF-HFP))/V2AlC MAX composites, in this study, we explored the novel P(VDF-HFP)/V2AlC MAX/montmorillonite (MMT) ternary composites. Compared with binary composites, the ternary composites showed the mildly reduced dielectric constant, significantly decreased dielectric loss and conductivity. Using highly-conductive V2AlC MAX filler aimed at taking advantage of the polymer/MAX interface polarization to increase the dielectric response of composites. Employing well-insulating MMT filler aimed at reducing the interface electric leakage conduction. At 1 kHz, the outstanding ternary composite with 2 wt% MMT and 20 wt% MAX could exhibit a high dielectric constant of ca. 27 and low dielectric loss of ca. 0.21. This work might offer a new research idea for the construction of high-performance composite dielectric films containing modern MAX ceramic fillers. [GRAPHICS] .
