摘要

介绍了一种新型的钛酸钡/碳纳米管（BTO/CNTs）压电薄膜的制备方法及其特性研究

利用BTO纳米颗粒、CNTs和聚二甲基硅氧烷（PDMS）作为原材料

采用改进的sol-gel法制备出厚度均匀的复合薄膜

使用油浴极化法在一定条件下对复合薄膜极化。并利用SEM表征制备复合薄膜的掺杂效果

发现CNTs的加入加快了电子的转移速率。在周期性的外力作用下

发现其电压输出波形符合阻尼振荡模型

并测试不同配比下复合薄膜的压电电压输出

得出最佳BTO/CNTs质量比为10∶1时

薄膜的输出电压最高可达4 V。

Abstract

A novel preparation method and characterization of barium titanate /carbon nanotubes（ BTO /CNTs）piezoelectric thin film is introduced

using BTO nanoparticles

CNTs and polydimethylsiloxane（ PDMS） as raw material

and composite thin films with uniform thickness are prepared by improved sol-gel method then polarized in an oil bath under certain conditions. Further

doping effect of the prepared composite thin films are characterized by SEM image and it is found that the added CNTs accelerate electron transfer rate. In periodic external force

the voltage output is found to be in accordance with the damping vibration model and the piezoelectric voltage output of composite film is measured in different matching. It is concluded that the best BTO / CNTs mass ratio is 10∶ 1 and output voltages of the film can reach to 4 V.
