【摘要】：采用半连续乳液聚合法合成出poly(St-co-BA-co-SAS)离子共聚物,进行了结构和形态表征;在其表面覆盖银修饰碳纤维(SM-CF)电极层,制得了新型离子共聚物复合电驱动材料(IPCEDM),降低了制备成本,并对其电驱动性能进行了研究。结果表明,以poly(St-co-BA-co-SAS)为基体的IPCEDM具有良好的电能—机械能转化机制,其初始形变速度、形变时间和最大形变角度均随工作电压(3~7V)的升高而增大;含水量是影响其电驱动性能的重要因素,提高含水量(38%,42%,51%)能够有效提升其电驱动性能和离子交换性能。
[Abstract]:The structure and morphology of polybutadiene St-co-BA-co-SAS ionic copolymers were synthesized by semi-continuous emulsion polymerization, and a new type of ionic copolymers composite electric driving material, IPCEDMN, was prepared by covering the silver modified carbon fiber SM-CFC electrode layer on its surface, which reduced the preparation cost. The electric drive performance is also studied. The results show that the IPCEDM based on Polymer St-co-BA-co-SASs has a good mechanism of electric-mechanical energy conversion. The initial deformation rate, deformation time and maximum deformation angle increase with the increase of the working voltage. Water content is an important factor affecting its electric driving performance. Increasing water content can effectively improve its electrical driving performance and ion exchange performance.
