Poly(vinylidene fluoride) (PVDF) based nano dielec. composites have been investigated widely due to their potential application in sensors, actuators, and energy storage fields. To achieve these goals, a novel modification of PVDF electroactive films was prepared due to the exfoliated and oriented Na+-MMT with the assistance of different cationic chain length imidazole-based ionic liquids The results proved the ion exchange between Na+-MMT and ILs promoted exfoliation and uniform dispersion of Na+-MMT in PVDF matrix efficiently even under a low ILs content (<0.05%). Furthermore, the existence of ILs and shearing force contributed to the oriented dispersion of Na+-MMT. The synergistic effect of Na+-MMT and ILs induced the crystal conformation transition from non-polar α-crystal to electroactive β/γ crystal. Compared with pure PVDF, PVDF/Na+-MMT/ILs nanocomposites with longer cationic chain ILs showed higher dielec. constant, breakdown strength, and energy d., while kept low-dielec. loss and conductivity The improved compatibility between PVDF and Na+-MMT due to the ion exchange and decreased crystal size for the polar β/γ crystal enhanced the transparency and elongation at break of PVDF/Na+-MMT/ILs nanocomposites significantly. The results proved [C16MIM][Cl] behaved optimum synergistic modification effect for the nanocomposites, and which showed potential applications in dielec. energy storage and microelectronic fields.
