A percolative poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene)/carbon black nanocomposite was fabricated via a simple solution blending method. The dielectric properties, mechanical properties, and breakdown strength were comprehensively investigated for electrostrictive applications. The nanocomposites exhibit excellent mechanical properties and dielectric properties with a dielectric permittivity of 140 and a low dielectric loss of 0.05 at 100 Hz. The significant enhancement of dielectric properties was explained by percolation theory, and a percolation threshold of 4.68 wt.% was observed. Breakdown strength results were analyzed by Weibull probability, and the observed inevitable decrease of breakdown strength limits its practical applications.
