Effects of Piezoelectric Ceramic Powder Content and Surface-Attaching Microparticles on Properties of 0-3 Type Piezoelectric Composite

摘    要
以超声清洗前后的PbZr0.49Ti0.51O3(PZT)压电陶瓷粉与聚偏二氟乙烯(PVDF)为原料,采用流延法制备了不同陶瓷粉含量的0-3型PZT/PVDF压电复合材料,研究了陶瓷粉含量及表面附着微粒对压电复合材料性能的影响。结果表明:未超声清洗的陶瓷颗粒表面附着有陶瓷微粒,超声清理后陶瓷微粒基本被去除;压电复合材料的相对介电常数和压电常数均随陶瓷粉含量的增加而增大;陶瓷颗粒表面无附着微粒时所得压电复合材料的相对介电常数和压电常数均高于表面有附着微粒的,且相对介电常数差值和压电常数差值均随陶瓷粉含量的增加而增大。

Abstract
With PbZr0.49Ti0.51O3 (PZT) piezoelectric ceramic powder before and after ultrasonic cleaning and polyvinylidene fluoride (PVDF) as raw materials, 0-3 type PZT/PVDF piezoelectric composites containing different content of ceramic powder were prepared by flow casting method. The effects of ceramic powder content and surface-attaching microparticles on the properties of the piezoelectric composite were studied. The results show that the surface of the ceramic particles was attached with ceramic microparticles without ultrasonic cleaning, and the ceramic microparticles were almost removed after ultrasonic cleaning. The relative dielectric constant and piezoelectric constant of the piezoelectric composites increased with the increase of ceramic powder content. The relative dielectric constant and piezoelectric constant of the piezoelectric composite obtained with ceramic particles without surface-attaching microparticles were higher than those with surface-attaching microparticles; the difference values of the relative dielectric constants and of the piezoelectric constants increased with the increase of ceramic powder content.
