Paper Title:
Dependence of Aspect Ratio on1-3 Polymer/Cement Based Piezoelectric Composite Properties
  Abstract

Piezoelectric ceramic(lead niobium lithium zirconate titanate, P(LN)ZT), sulphoaluminate cement and polymer were used to fabricate 1-3 polymer/cement based piezoelectric composites by cut-filling technique. The influence of P(LN)ZT aspect ratio on the piezoelectric and dielectric properties of composites was investigated. The results show that as the P(LN)ZT aspect ratio increases, the piezoelectric strain factor d33 and relative dielectric factor εr decrease evidently, while the piezoelectric voltage factor g33 decreases slowly. The acoustic impedance Z is hardly influenced by the aspect ratio. At the same time, the influence of temperature on the dielectric properties of the composites was studied. The results show that with increasing the temperature at the frequency of 1kHz and 150 kHz, the dielectric factor εr exhibits the trend of increase. In the range of -40°C-110°C, the dielectric loss tanδ first increases slowly, but when exceeding the temperature of 80°C, it increases evidently. Comparing with P(LN)ZT piezoelectric ceramic, the vibration at thickness mode of 1-3 type piezoelectric composite is strengthened.
