纤维素基电致驱动器结构可能性与影响因素分析

Possibilities as Actuator and Analysis of Influence Factors on Cellulose Based Electro-Active Paper

验证了电致驱动纸(Electro-Active Paper-EAPap)作为驱动器的可能性,同时对其驱动影响因素进行了讨论。EAPap驱动器以纤维素基材料-纸制品作为基体,在基体两面层压了银质电极构成。当在电极上施加一个适当的电压时,EAPap驱动器将产生伸缩、弯曲等位移。实验结果表明,EAPap的驱动性能依赖于样品形式的选取,适宜的驱动电压和驱动频率,同时环境因素对驱动器性能的影响至关重要。另外,在对EAPap驱动器的驱动影响因素的研究中发现,胶的品种也对EAPap驱动器的驱动效果有一定的影响。研究结果表明,EAPap驱动器的电致驱动效应属于电致收缩效应。由于EAPap很容易制造而且轻便,很多领域可以得到应用,如柔性扬声器、活性吸音材料和智能成型控制元件等。

The possibilities as actuator on cellulose-based Electro Active Paper(EAPap) were investigated through the experiments in this paper.At the same time,the influence factors on the actuation of actuator were discussed as well.The base of Eapap actuator was built by cellulose based material-Paper,two silver foils were laminated on both sides of the base as electrodes.When certain voltage was applied on the electrodes,stretch and bending were observed.The results show the actuating performance is correlated wit...
