中文摘要：

用红外光谱、扫描电镜表征了介电弹性体VHB4910在不同预拉伸条件下的结构和形貌;用能谱分析了柔性电极导电膏中元素的种类和数量;在优化条件下由VHB4910和柔性电极制备了电致动驱动器,测试了其应变响应特性,并在柔性电极中加入0.3%的银粉进行相关对比实验.研究表明：VHB4910经等轴预拉伸后,材料表面更均匀,应变效果更好;在加压5 kV时,未添加银粉的柔性电极制作的电致动驱动器能产生更大变形量,为149.8%,推测其与“量子隧道效应”有关.

Abstract： The structure and morphology of the dielectric elastomer VHIM910 under different pre-stretching condi- tions were characterized by means of IR and SEM, and the types and amounts of the elements in the conductive paste of flexible electrodes were analyzed by using an energy dispersive spectrometer. Then, by using VHB4910 and flexible electrodes, an electroactive actuator was prepared under the optimized conditions, and its strain re- sponse characteristics were tested. Moreover, the electroactive actuator with O. 3% silver in flexible electrodes was compared with that with the flexible electrode free of silver by an experiment. The results show that, after the iso- metric pre-stretching, VHB4910 has a more uniform surface with a better strain, and that, at the voltage of 5 kV, the electroactive actuator with the flexible electrode free of silver has a larger deformation of up to 149.8%, which may be related to ＂the quantum tunnel effect＂.
