锆钛酸铅纳米管制备工艺研究

Preparation Process of PZT Nanotubes with AAO Template

摘要:

研究了溶胶-凝胶浸渍阳极氧化三氧化二铝（AAO）模板法制备Pb(Zr0.52Ti0.48)O3（PZT）一维纳米结构的工艺方法。试验结果表明，以硝酸氧锆、醋酸铅、钛酸丁酯（按0.52:1:0.48的摩尔配比）为原料，以乙二醇为溶剂，可获得稳定的PZT溶胶，通过反复滴加浸渍氧化铝模板，最终经650 ℃晶化处理和腐蚀AAO后得到PZT纳米管。样品表征结果说明，制得的PZT纳米管为钙钛矿相，表面结构完整、孔径均一、排列均匀整齐，长50 μm、管径300 nm、壁厚40 nm。

Abstract:

The preparation process of one dimensional nanostructure Pb(Zr0.52Ti0.48)O3 (PZT) using sol-gel dipping of anodized aluminium oxide (AAO) template was studied. Results show with zirconium oxynitrate, lead acetate and tetrabutyl titanate as raw materials (Zr:Pb:Ti=0.52:1:0.48) and ethylene glycol as solvent, stable and lasting PZT sol was obtained. Then the sol was injected into the hard template followed by the crystallization step at 650 oCo and corrosion of AAO; finally the PZT nanotubes were prepared. The characterization results shows the PZT nanotubes products are perovskite, with structurally integrated surface, uniform aperture and ordered arrangement, and their length is 50μm, the diameter 300 nm and the thickness 40 nm.
