Mechanical and Electrical Properties of Electroactive Papers and its Potential Application

文专注于电致驱动纸的机电特性进行研究。电致驱动纸结构能够在相当低的电压下以较低的功率消耗,产生比较大的弯曲位移变形。电致驱动纸是一种复杂的各项异性材料,目前还没有对其进行广泛的定量特征化分析,在电致驱动纸能够应用在驱动器结构之前还要进行基本的机电性能测试与分析。经计算电致驱动纸的杨式模量的变化范围为5～8GPa。热机械分析被用来确定由于去水化以及最大应用温度而影响尺寸变化程度的因素。通过测试样品的关键特性,提供一种测试该材质疲劳特性的一种方法。基于频率的电阻抗分析和介电特性测试也是分析者确定电致驱动纸的电特性。最后利用测试并计算样品顶部的位移大小、阻滞力以及消耗的电功率,来检验电致驱动纸的性能。

This paper focuses on the research of mechanical and electrical characteristics of electro-active paper （EAPap）. EAPap can undergo a large bending displacement at a relatively low voltage under low power consumption in dry conditions. The EAPap is a complex anisotropic material, which has not been extensively characterized and additional basic and design testing are required before developing application devices from EAPap. By calculating, the initial Young＇s modulus of EAPap is in the range if 5-8GPa. The thermo-mechanical analysis of EAPap is investigated to determine such factors as the degree of dimensional change due to dehydration and the maximum use temperature. Fatigue test identifies critical properties of this under-analyzed class of materials to provide a measure of its fatigue capabilities. The electrical impedance analysis and dielectric property measurement with frequency are also important information that allows us to characterize the electrical behavior of EAPap. Finally, the performance of EAPap is measured in terms of tip displacement, blocking force and electrical power consumption.
