Description
Summary:The effect of the structure of the piezoceramics on the dielectric and strength properties of a composite based on polyvinylidene fluoride was studied. It is shown that the dielectric strength ɛ, tanδ, and logρ v correlate as dependent on the electric field intensity during the electric treatment. It is assumed that the correlation between the electric and mechanical strength is related to a change in the physical structure of the polymer matrix and the boundary layer of the composite components. The causes for a change in the charge value as dependent on the filler’s structure are found.
