Preparation and Characterization of Ordered Pb(Zr0.53Ti0.47)O3 Nanotube Arrays by Sol-Gel Template Method
Ferroelectric lead zirconate titanate Pb(Zr0.53Ti0.47)O3 (PZT) nanotubes were prepared using porous anodic aluminum oxide (AAO) template by means of a simple sol-gel method. Scanning electron microscope (SEM) showed that closely packed PZT nanotubes were synthesized with a high pore-filling rate and aspect ratio after annealing at 700 °C. The X-ray diffraction investigations revealed that the annealed PZT nanotubes exhibit a polycrystalline microstructure and were composed of perovskite crystal structure. The results of polarization hysteresis and piezoresponse force microscope (PFM) measurements showed typical piezoelectricity in PZT nanotubes as well as stable electrical properties revealed by leakage current measurement, indicating potential applications using ferroelectric one-dimension nanostructures.
