Influence of polyaniline on the electrophysical properties of lead-free ceramics

The effect of polyaniline additives on the dielectric and piezoelectric properties of a composite based on a multi-component system of sodium-potassium niobate was studied in the paper. The behavior of dielectric characteristics, electromechanical and piezoelectric properties of the system was studied. The critical concentration of polyaniline influencing the formation of an electromechanical connection between ferroactive inclusions and piezoelectric properties was determined.
