    Abstract

    The authors report the finding of large enhancement in the electric energy density and electric displacement level in nanocomposites of poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) relaxor ferroelectric polymer/ Zr O2 nanoparticles. Through the interface effect, the presence of the nanoparticles (with only 1.6 vol % of ZrO2 nanoparticles in the composite) raises the maximum electric displacement D from 0.085 C m2 under 400 MVm in the neat terpolymer to more than 0.11 C m2 under 300 MVm in the nanocomposites. Consequently, a high energy density of 10.5 J cm3 can be achieved under a lower field (300 MVm) in the nanocomposites compared with the neat terpolymer.
