1-3压电复合材料的压电、介电及铁电性能要远远优于0-3压电复合材料.在制备传统的0-3复合材料过程中引入电泳技术,使得压电颗粒在聚合物基体中取向排列,制备得到伪1-3复合材料.实验结果表明:在制备PZT/环氧树脂0-3复合压电材料固化过程中,采用500 V/mm,4 kHz的电场对其进行电泳辅助取向,可使得颗粒呈现珍珠串状排列,得到伪1-3复合材料;其压电、介电、铁电性能均比原来的0-3复合材料有显著的提高.电泳辅助制备技术用于制备伪1-3复合压电材料具有操作简单、成本低廉、压电、介电、铁电性能显著提高等优点,在智能传感领域具有很好的实际应用前景.
1-3 Piezoelectric composite piezoelectric, dielectric and ferroelectric properties far better than the 0-3 piezoelectric composite materials in the preparation of traditional 0-3 composite materials introduced electrophoresis technology, making the piezoelectric particles in the Pseudo 1-3 composites were prepared by the polymer matrix orientation.The experimental results show that during the curing process of PZT / epoxy 0-3 composite piezoelectric material, a 500 V / mm, 4 kHz electric field Electrophoretic assisted orientation can make the particles appear pearl string-like arrangement, to get pseudo-1-3 composite materials; its piezoelectric, dielectric, ferroelectric properties than the original 0-3 composite material significantly improved electrophoresis assisted preparation techniques The prepared pseudo-1-3 composite piezoelectric material has the advantages of simple operation, low cost, remarkable improvement of piezoelectric, dielectric and ferroelectric properties, and has good practical application prospect in the field of intelligent sensing.
