采用改进的凝胶注模成型方法，在低粘度、高固相含量的锆钛酸铅（PZT）悬浮液中，原位聚合乙内酰脲环氧树脂和3，3 ′-二氨基二丙胺（DPTA），制备了微尺度随机1-3型压电阵列。流变学结果表明，乙内酰脲环氧树脂浓度对预混液的粘度影响不大，因此，当树脂质量分数为15.0%时，悬浮液的最佳固含量可达55.0vol%。Weibull分析还表明，从55.0体积%的PZT悬浮液获得更均匀的显微结构，其中Weibull模量和特征弯曲强度达到最大值12.57和80.94 MPa。成功地制备出了具有上级结构完整性和高保真度的无规压电柱阵列。
A modified gelcasting approach was used to fabricate the microscale randomized 1–3 piezoelectric array, which.involves the in situ polymerization of hydantion epoxy resin and 3,3′-Diaminodipropylamine (DPTA) in the lead.zirconate titanate (PZT) suspensions with low viscosity and high solid loading. Rheological results demonstrated.that the hydantion epoxy resin concentration had little effect on the viscosity of the premix solution, and.therefore the optimized solid loading of the suspensions with 15.0 wt% resin could reach as high as 55.0 vol%..Weibull analysis also revealed that a more homogenous microstructure was obtained derived from the 55.0 vol%.PZT suspension, where the Weibull modulus and the characteristic flexural strength reached the maximum.value of 12.57 and 80.94 MPa. The excellent randomized piezoelectric pillar array with superior structural.integrity and high fidelity was successfully fabricated.
