Latest Patents

Pismany's latest patents include a method of electrophoretic deposition of ferroelectric films using a tri-functional additive. This innovative method enhances the deposition of ferroelectric particles on substrates, allowing for the creation of high-quality films or stand-alone bodies. The process utilizes a tri-functional phosphate ester additive in concentrations below 10 volume percent, eliminating the need for additional binders. The method involves preparing a suspension of ferroelectric particles, such as commercially available PZT powder, in a polar solvent like ethanol, followed by the addition of the phosphate ester additive and ultrasound treatment. The resulting suspension is employed in the electrophoretic deposition of ferroelectric particles onto a prepared substrate. After the deposition, the green film undergoes drying and high-temperature sintering. The outcome is a diverse range of piezoelectric products characterized by exceptional uniformity, thickness distribution, and reproducibility.
