Abstract: The nonlinear dielectric permittivities of 0-3 composite films of lead titanate (PT) nanoparticles in 56/44 mol % polyvinylidenefluoride trifluoroethylene (PVDF-TrFE) with 0.08 and 0.27 ceramic volume fractions and with various polarization states (only the matrix or the inclusions polarized, or the two phases polarized in parallel or antiparallel directions) have been investigated. An effective medium model for the dielectric nonlinearities of nonlinear inclusions in a nonlinear matrix has been developed. The theoretical predictions are found to be in good agreement with the experimental results. Comparing the composite dielectric nonlinearities with experimental data of the pure PVDF-TrFE copolymer gives access to the nonlinear properties of the PT nanoparticles.
