Field-induced phase transitions and dielectric energy density in poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) terpolymer

Accepted: 3 August 2010
Field-induced polarization, dielectric response and dielectric energy density of poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene) terpolymer were investigated. In charging and discharging circles, two dielectric peaks exist at 70 MV/m and 35 MV/m, showing two field-induced phase transitions. The giant electrical energy densities of the terpolymer should be attributed to the rapid change of polarization in the field-induced ferroelectric phase.
