The study was made on the influence of the structure of piezoelectric ceramics on dielectric and mechanical properties of compositions based on polyvinylidenenfluoride. It is shown that there is a correlation between the dielec- tric strength, ε, tgδ and lgρv against the strength of electric treatment. It is assumed that the correlation between the elec- trical and mechanical strength is due to the change in the physical structure of the polymer matrix and boundary layer components of the compositions. The reasons of a change in the charge depending on the structure of the filler were found out.
