Electrophoretic Growth of Lead Zirconate Titanate Nanorods

Abstract

Nanorods of lead zirconate titanate (PZT)—a ferro‐ and piezoelectric material—up to 10 μm in length and 70 to 150 nm in diameter are produced by sol‐gel electrophoresis of PZT in a track‐etched polycarbonate membrane, which is used as a template. The Figure gives a close‐up view of a PZT film with nanowires attached, as obtained after pyrolytic removal of the organic template.

A Study on the Influences of Processing Parameters on the Growth of Oxide Nanorod Arrays by Sol Electrophoretic Deposition

“…The preparation of TiO 2 sol has been reported in Ref. 12, similar to the process reported previously [10,11]. Briefly, the sols were prepared as follows.…”

“…The electric fields applied for the growth of nanorod arrays varied in the range of 0-6 V/cm. Detailed set-up can be found in our previous publications [7,[10][11][12]. After the growth of nanorod arrays, the filled templates were dried at 100…”

“…The technique of sol electrophoretic deposition in templates provides a versatile method for forming nanorods of numerous simple and complex oxide nanorods [5][6][7][8][9], and while sol electrophoretic deposition has been known for some time as a technique for the formation of films, only recently has it been adapted for the formation of nanorods [10,11]. In concept, the only requirement is that one applies an electric field to an electrostatically stabilized sol.…”

One-Dimensional Titanium Dioxide Nanomaterials: Nanotubes

“…Namely, porous alumina membranes 70,[74][75][76][77][78]616 and ZnO nanorods/wires 617 have very frequently served for this purpose. Overall, DSSCs produced using such TiO 2 nanotubular structures typically show a 3-5 % conversion efficiency.…”

Ferroelectric nanoparticles, wires and tubes: synthesis, characterisation and applications

“…BaTiO3, PbZr1-xTixO3, SrTiO3, are the most extensively investigated 85 material due to their excellent ferroelectric characteristics. 17,19 Although PbZr1-xTixO3 nanowires were the first 1D structures to be synthesised, 153,154 BaTiO3 nanowires were the first to be studied for their size-dependent ferroelectric behaviour 54 Figure 3 shows SEM and TEM images of different forms of pervoskite-based ID ferroelectric nanostructures synthesised recently by various template-free methods. Hydro/solvothermal 15 synthesis has been effectively utilised for synthesising complex pervoskite ferroelectric nanowires and tubes, owing to the homogeneous mixing of individual reactants under subcritical conditions.…”
