Abstract: The theoretical aspects of the viscoelastic model for polarization switching in “soft” organic ferroelectrics have been considered. The model describes the amplitude-frequency dependences of the hysteresis loops obtained upon polarization switching in thin films of the ferroelectric copolymer poly(vinylidene fluoride-trifluoroethylene).
