Abstract Sol-gel synthesis has been a very successful and efficient route for obtaining high quality ferroelectric/piezoelectric materials. Piezoelectric nanostructures, however, constitute a very recent field of research and special emphasis must be put on optimizing the packing of particles inside the nanoporous matrix in order to obtain nanomaterials with potential use on practical applications. In this work we study the influence of some critical sol features (aging time and concentration) on several interesting parameters when considering the electrophoretic insertion of Lead Titanate Zirconate (PZT) 53/47 nanoparticles in a Porous Anodic Alumina matrix. Our study focuses on pH, Zeta potential, Liquid Surface Tension, Mean Nanoparticles Size and Crystallization Routes. According to our results, and despite some previous reports, a successful electrophoretic deposition can be carried out on a wide range of concentrations and aging times. [ABSTRACT FROM AUTHOR] |
