Wetting of the pore walls of porous templates is a simple and convenient method to prepare nanotubes. Ferroelectric lead zirconate titanate and barium titanate nanotubes were fabricated by wetting of porous silicon templates of polymeric precursors. The ferroand piezoelectric properties of an individual ferroelectric either of a PZT or a BaTiO3 nanotube were electrically characterized by measur...

Abstract In this study, graphene particles are introduced to the lead magnesium niobate-lead titanate and polyvinylidene fluoride (PVDF) form a flexible ternary composite. The concentration is rigorously designed morphologically optimized, warranting good piezoelectric dielectric properties. performances greatly increased compared with pure PVDF films. Then theoretical model formulated quantita...

The adsorption and reaction in supercritical CO2 of the titanate coupling reagent NDZ-201 on the surfaces of seven metal oxide particles, SiO2, Al2O3, ZrO2, TiO2 (anatase), TiO2 (rutile), Fe2O3, and Fe3O4, was investigated. FTIR and TG analysis indicated that the adsorption and reaction were different on different particle surfaces. On SiO2 and Al2O3 particles, there was a chemical reaction of ...

Titania (TiO2) and sodium titanate nanostructures with controllable phases and morphologies were synthesized by a hydrothermal method with titanium disulfide (TiS2) as the starting material. Sodium titanate nanobelts could be synthesized under a relatively low alkaline concentration (1 mol L(-1) NaOH) and short duration (6 h). At 3 mol L(-1) HCl, rutile TiO2 nanorods were synthesized. Anatase T...

The common facets of anatase crystals are the (001) and (101) planes. However, the phase transformation from lepidocrocite-type titanate into anatase by hydrothermal processing yields an anatase microstructure with high concentration of exposed (010) planes. The phase transformation of a lepidocrocite-type protonated layered titanate (HTO) into anatase was studied using XRD, TEM, FTIR, and meas...

a Titania (TiO 2) and sodium titanate nanostructures with controllable phases and morphologies were synthesized by hydrothermal method with titanium disulfide (TiS 2) as the starting material. Sodium 5 titanate nanobelts could be synthesized under a relatively low alkaline concentration (1 mol L-1 NaOH) and short duration (6 hours). At 3 mol L-1 HCl, rutile TiO 2 nanorods were synthesized.
