Description

一种无铅压电纳米阵列及其制备方法
技术领域
本发明涉及的无铅铁电材料，具体是一种ABO3型钙钛矿结构，无铅压电纳米阵列及其制备方法。
背景技术
—维压电纳米结构主要包括纳米管，纳米纤维，纳米线以及量子点等。与薄膜不同，纳米线、纳米管等一维材料有更高的比表面积，更高的长径比，具有比薄膜和纳米颗粒更优异的性质，可以大幅缩小器件体积、提高性能，便于集成化制造。而且这些结构不仅具有一些特殊特点如晶体学取向，混合相组成，电畴结构，以及有限尺寸的极化响应等，而且还具有某些特殊的效应例如表界面效应，隧道效应，半导体性铁电体的电子运输等很可能使得铁电一维纳米材料在性能上发生质的变化。一维纳米材料的合成方法有很多种，早期的有纳米平板印刷术如电子束离子束刻蚀、射线或远紫外光刻等，目前兴起的还有化学法。通过纳米平板印刷术制备一维纳米材料的目标性强，而且可以较好的控制材料的微观尺寸，但是这一类方法存在着普遍的缺陷，即生产成本过高且不易实现工业生产。
常见的纳米阵列化学合成方法有模板法、金属溶盐法、水热法和溶胶凝胶法等。但是这些制备方法对材料的种类、生产成本、材料产量和产率方面的都存在不足。通过固相烧结结合热处理制备无铅压电纳米阵列还未见报导。

本发明一种无铅压电纳米阵列，材料组成为：
0.9Bi0.5Na0.5TiO3-0.1Bi2(Mn4/3Ni2/3)O6。
本发明无铅压电纳米阵列的制备方法，采用传统陶瓷烧结法，结合热处理技术，具体包括如下步骤：
(1)按照Bi0.5Na0.5TiO3的化学计量分别称取分析纯原料Bi2O3、Na2CO3和TiO2，装入球磨罐中，以氧化锆为磨球、无水乙醇为球磨介质，充分混合球磨24小时，分离磨球，将原料在60℃烘干，再在高铝坩埚中于850℃保温2小时预合成Bi0.5Na0.5TiO3粉体；
(2)按照Bi2(Mn4/3Ni2/3)O6的化学计量分别称取分析纯原料Bi2O3、NiO和MnO2，装入球磨罐中，以氧化锆为磨球、无水乙醇为球磨介质，充分混合球磨24小时，分离磨球，将原料在60℃烘干，再在高铝坩埚中于760℃保温2小时预合成Bi2(Mn4/3Ni2/3)O6粉体；
(3)将合成好的Bi0.5Na0.5TiO3、Bi2(Mn4/3Ni2/3)O6粉体，按照0.9Bi0.5Na0.5TiO3-0.1Bi2(Mn4/3Ni2/3)O6化学计量式配料，以无水乙醇为介质球磨15h，干燥，加入5%的PVA造粒；在100Mpa压力下冷等静压成型；
(4)成型的原料采用微波烧结，990℃保温20分钟，烧结成瓷；
(5)烧结的样品放在氧化锆板上，上面覆盖氧化铝板，58℃/min快速升温至635℃保温95分钟，然后随炉冷却至室温，通过热处理的样品生长成无铅压电纳米阵列，其中纳米线长度在2-10μm，直径为60-800nm。
