Research output: Contribution to journalConference article


Low-density piezoelectric ceramics were prepared by sol-gel technology. These ceramics with special properties are aluminosilicate aerogels. In order to reinforce the fragile aerogels, the inorganic component was combined with organic polymers during the gelling procedure. The composite gels are proved to be piezoelectric. It was found that the structure and porosity of aerogels have strongly influenced the piezoelectricity of aluminosilicate aerogels. The supramolecular structure of these aerogels investigated by small angle X-ray scattering (SAXS) has been shown to be fractal-like. It seems that the piezoelectric effect can be related to the porous fractal structure of the aerogels.
