摘要

以锆钛酸铅(PZT)陶瓷粉和聚3-羟基丁酸铅(PHB)为材料,通过机械混合,在180℃高压下压制,制备了具有弹性的压电复合材料立膜。研究了压电系数d/sub 33/随PZT含量、极化温度和电场的变化规律。当PZT含量为50vol %时,d33系数的最大值约为6pC/N。由于PHB是一种可生物降解的聚合物,该复合材料作为传感器具有潜在的应用前景,可以最大限度地减少环境问题。

PHB/PZT composite
Flexible standing films of piezoelectric composite made of lead zirconate titanate (PZT) ceramic powder and poly(3-hydroxybutyrate) (PHB) in powder form were obtained by mixing both polymers mechanically and pressed at 180 /spl deg/C. The piezoelectric coefficient d/sub 33/ were investigated as function of PZT content, poling temperature and electric field. The highest value for d33 coefficient was around 6pC/N for 50 vol% of PZT content in the composite. As PHB is a biodegradable polymer the composite has potential application as sensor minimizing the environmental problems.
