Abstract :
A novel type of flexible composite electret film based on the polymer PVDF (polyvinylidine fluoride) and compounded with the ferroelectric ceramic PCM system is discussed. Details are presented relative to methods of preparation, physical and mechanical properties, and structural analysis. It is shown that ferroelectric polarization charges under the action of PCM´s strong piezoelectric effect lead to compound nonhomogeneous coupling
