| 제목 | Hydrothermal Synthesis of 1-D ferroelectric perovskite materials on substrate |
| 초록 | Barium titanate and lead titanate is representative famous ferroelectric materials. In particular, one-dimensional (1-D) ferroelectric nanomaterials on substrates are of great interest because of their peculiar physical properties of large surface area, excellent charge transport and outstanding ferroelectric properties. The research of 1-dimensional ferroelectric materials is progressing because they are applicable to various fields. We synthesized BaTiO3 on FTO glass and PbTiO3 nanowires on Ti substrates. In case of BaTiO3 nanowires, we utilized the TiO2 nanoparticles thin film from spray coating and Ba(OH)2 under strong alkaline condition using ammonia. we synthesized vertical aligned PbTiO3 nanowire array on Ti substrate with high aspect ratio via hydrothermally breaking the TiO2 nanotubes which was fabricated by anodic oxidation of Ti foil. The as-obtained nanowires were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), synchrotron X-ray diffraction, X-ray photoelectron spectroscopy (XPS) and EXAFS. And we also investigated capacitance and piezoforce properties. |
