摘要:本文研究了溶胶-凝胶浸渍阳极氧化三氧化二铝(AAO)模板法制备Pb()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(:1:)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微米、管径300纳米、壁厚40纳米。

Abstract: The author of this paper studies the preparation of one dimensional structure of the Pb()O3(PZT)using the Sol-gel method with anodized aluminium oxide (AAO) experiment shows using zirconium oxynitrate, lead acetate and tetrabutyl titanate as raw materials(Zr:Pb:Ti=:1:) and ethylene glycol as solvent,we can get very stable and lasting PZT sol. And using dropping and soaking method to inject the sol into the hard template,then through the crystallization step at 650℃ and corrosion of AAO step we will get the PZT nanotubes in the end. The characterization results shows the product PZT nanotubes are pervoskite, surface structurally integrated, aperture uniform, uniformly arranged, 50um-long, diameter of 300nm and thickness of 40nm.
