以镁酸铅压电陶瓷粉体（PMN）为分散相，在丁腈橡胶（NBR）基体中制备了一种具有特殊压电性能的复合材料。研究了复合材料的介电和压电性能。结果表明，80%的PMN陶瓷粉体的粒径为0.5 ~ 2 μm。复合材料的压电常数（d33）随着PMN体积分数的增加而增大，当PMN体积分数为85%时，复合材料的压电常数达到最大值33。随着极化电压的增加，适当延迟极化时间有助于提高d33值。可选的偏振条件为25分钟、7-8 μ m/mm和80°C。介电常数随着PMN体积分数的增加而增加。极化时间、极化电压和极化温度对介电常数没有影响。
A new composite with special piezoelectric property was prepared by using lead magnesio-niobate piezoelectric ceram powders (PMN) as dispersing phase in acrylonitrile butadiene rubber (NBR) matrix. The dielectric and piezoelectric properties of the composite were studied. The result shows that the particle size of 80% of PMN ceram powders was 0.5–2 µm. The piezoelectric constant (d33) of the composite increased with increasing volume fraction of PMN, and the max piezoelectric constant is 33 when the PMN volume fraction is 85%. Appropriate delay of polarizing time with increasing polarizing voltage could be helpful to improve the d33 value. The optional polarizing condition is 25 min, 7–8 kv/mm, and 80°C. The dielectric constant increased with the increasing of the PMN volume fraction. Polarized time, polarized voltage, and polarized temperature have no effect on the dielectric constant.
