ABSTRACT:
A hybrid piezoelectric composite comprises a layer of a polymer matrix comprising particles of a PZT group in a micro range of dimensions, which is sandwiched between two layers of a polymer matrix comprising particles of a dielectric material in a nano range of dimensions. The materials of both layers are polarized with electrothermal polarization. The polymer matrices of both component composites may comprise high-density polyethylene, polyvinylidene fluoride, polypropylene, or low-density polyethylene. The dielectric material of the first component nanocomposite may be selected from the group consisting of SiO2and BaTiO3, and the ceramic particles of the second component are made from a piezoelectric ceramic material of a PZT group having a tetragonal structure.
