Research on Viscoelasticity and Application Characteristic of Dielectric Elastomer

电场活化聚合物是一种具有黏弹性力学行为和超弹性力学行为双重特性的高分子聚合物材料,通过电场聚合物黏弹性特性研究,构建黏弹性响应模型,并根据试验数据研究薄膜材料蠕变和松弛特性,估算出电场活化聚合物黏弹性特征时间常数,为该类器件性能研究提供一定的理论基础。

Dielectric Elastomer（DE）is a kind of polymer material with the properties of viscoelasticity and superelasticity.Through the study on viscoelastic theory,the viscoelasticity model of DE was set up,the model parameters were regressed according to the experimental data,and the time constant of viscoelastic characteristic of DE material was estimated.Thus the application characteristics of DE actuator device were explained theoretically,which provided a theoretical basis for the performance research of the device.
