摘　　要：综合利用铌镁锆钛酸铅(PMN)压电陶瓷、互穿聚合物网络(IPN)两种材料各自的优点,设计制备了以丙烯酸酯IPN体系为基体的聚合物基压电阻尼复合材料。研究发现:PMN的加入,不仅提高了其阻尼性能,对复合体系的热稳定性也有贡献。经万能击穿装置极化后,研究压电常数与PMN含量的关系,用动态力学分析仪研究发现其阻尼性能更加优越。IPN/PMN piezoelectric intellectual damping material was in view of the respectively prominent merits of lead niobium-magnesuim zirconate-titanate （PMN） piezoelectricity ceramics and interpenetrating polymer networks （IPN）. It was discovered that the PMN joining,not only enhanced its damping performance,also had the contribution to the compound system thermostability. After polarization with the multi-purpose penetrates installment, the properties of these composites were investigated with dynamic mechanical analyze. Its damping performance was more superior.
