将具有优异导电性能的碳纳米管（CNT)与压电材料钛酸钡（BTO)复合于高分子有机材料聚二甲基硅氧烷（PDMS)中，制备出了具有低内阻的柔性复合压电薄膜，研究了制备的薄膜在不同极化条件下的开路电压以及不同体积配比的BTO/CNT压电薄膜的电导率。实验结果表明，在电场为3．6 kV/mm、温度是90℃、时间为60 min的极化条件下，当BTO与CNT的体积比N为2：3以及BTO与CNT混合颗粒占PDMS基体的总体积比V为8%时，能得到具有最佳电导率的复合压电薄膜。

A flexible piezoelectric composite film with low internal resistance was synthesized via mixing the multiwalled carbon nanotubes( CNT) with superior conductivity and piezoelectric materials BaTiO3 into the Polydime-thylsiloxane ( PDMS ) . The open-circuit voltage of the prepared flexible composite piezoelectric film was further researched under various polarization conditions. The influence of the ratio of the BTO/CNT in volume on the conductivity of the sample prepared was also investigated. These results obtained manifested that under the polarization condition of 3. 6 kV/mm,90 ℃ and 60 min,when the N equaled to 2:3(The volume ratio of BTO to CNT)and V was equivalent to 8%(the volume percentage of BTO and CNT mixtures/PDMS matrix),the composite piezoelectric film with optimum conductivity was achieved.
