摘要：采用碳纳米管对0-3-1型压电复合材料进行改性，研究了诱导极化电压（E1）、诱导电压方向、极化温度（T）、极化时间（t）、二次极化电压（E2）等相关因素对0-3-1型水泥基压电复合材料压电性能的影响，确定了0-3-1型水泥基压电复合材料最优的极化工艺和制备过程。结果表明，碳纳米管改性0-3-1型水泥基压电复合材料的最优诱导电场方向为与1型陶瓷柱夹角为30°方向，合理诱导电压为600 V/cm，合理二次极化电压为3 kV/mm，合理极化温度为100 ℃，合理极化时间为30 min。

Abstract：Carbon nanotubes were used to modify the 0-3-1 piezoelectric composites, and the induced polarization voltage（E1），induced voltage direction, polarization temperature（T），polarization time（t），and second pole were studied. The influence of relevant factors such as the voltage（E2） on the piezoelectric properties of the 0-3-1 cement-based piezoelectric composite material determines the optimal polarization process and preparation process of the 0-3-1 cement-based piezoelectric composite material. The results show that the optimal induced electric field direction of carbon nanotube modified 0-3-1 type cement-based piezoelectric composite material is 30° directions with the type 1 ceramic column，and the reasonable induced voltage is 600 V/cm. The secondary polarization voltage is 3 kV/mm，the reasonable polarization temperature is 100 ℃，and the reasonable polarization time is 30 min.
