摘要

采用溶液共混-压模法制备了钛酸铅(PT)/偏氟乙烯-三氟乙烯(P(VDF-TrFE))共聚物0-3复合材料。为了获得复合材料的压电和热释电活性,采用逐步极化方法对其进行极化。制备了具有(i)仅在陶瓷相中极化和(ii)在陶瓷和共聚物中平行极化的样品。测量了这两种复合材料的压电系数和热释电系数,并对结果进行了讨论。

Piezoelectric and pyroelectric properties of PT/P(VDF-TrFE) 0-3 composites
Lead titanate (PT)/vinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) copolymer 0-3 composites have been fabricated by solution blending followed by compression-molding. In order to obtain piezoelectric and pyroelectric activities the composites have been polarized by a stepwise poling method. Samples with (i) polarization in the ceramic phase only and (ii) parallel polarization in the ceramic and copolymer have been prepared. The piezoelectric and pyroelectric coefficients of these two types of composites have been measured and the results are discussed.
