本研究描述了新的致动器与纤维素纳米纤维，单壁碳纳米管和离子液体（CNFs/SWCNT/IL）和检查的电化学和机电性能的CNF/SWCNT/IL凝胶混合致动器。此外，存在于电极上的CNF物种和聚（偏二氟乙烯-共-六氟丙烯）（PVdF（HFP））或CNF/IL的电解质层物种对低电压电活性聚合物致动器的电化学和机电性能的影响进行了研究。CNF/SWCNT/IL结构揭示了高度缠结的CNF和SWCNT的网络。结果表明，CNF/SWCNT/IL电极和PVdF（HFP）/IL电解质致动器可以显著优于CNF/SWCNT/IL电极和CNF/IL电解质致动器。PVdF（HFP）被认为是比CNF更好的聚合物电解质。此外，这些CNF/SWCNT/IL电极致动器的位移响应的频率依赖性成功地模拟使用双层充电动力学模型。PVdF（HFP）/IL电解质致动器所表现出的等效电路模型与CNF/IL电解质致动器所表现出的等效电路模型不同。基于本研究的结果，CNF/SWCNT/IL电极和PVdF（HFP）/IL电解质致动器有希望作为电化学材料应用于现实世界的应用，包括可穿戴和能量转换设备。本研究描述了新的致动器与纤维素纳米纤维，单壁碳纳米管和离子液体（CNFs/SWCNT/IL）和检查的电化学和机电性能的CNF/SWCNT/IL凝胶混合致动器。
This study describes new actuators with cellulose nanofibers, single-walled carbon nanotubes and ionic liquids (CNFs/SWCNTs/ILs) and examines the electrochemical and electromechanical properties of CNF/SWCNT/IL gel hybrid actuators. Further, the effects of the CNF species present on the electrode and the electrolyte layer species of poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF(HFP)) or CNF/IL on the electrochemical and electromechanical properties of the low-voltage electroactive polymer actuators are investigated. The CNF/SWCNT/IL structure revealed a network of highly entangled CNFs and SWCNTs. The results indicated that the CNF/SWCNT/IL electrodes and the PVdF(HFP)/IL electrolyte actuators can significantly outperform the CNF/SWCNT/IL electrodes and the CNF/IL electrolyte actuators. PVdF(HFP) was considered to be a better polymer electrolyte than CNF. Further, the frequency dependences of the displacement responses of these CNF/SWCNT/IL electrode actuators were successfully simulated using a double-layered charging kinetic model. The equivalent circuit models exhibited by the PVdF(HFP)/IL electrolyte actuators are different when compared to those exhibited by the CNF/IL electrolyte actuators. Based on the results of this study, the CNF/SWCNT/IL electrodes and the PVdF(HFP)/IL electrolyte actuators are promising for application as electrochemical materials that are useful in real-world applications, including wearable and energy-conversion devices. This study describes new actuators with cellulose nanofibers, single-walled carbon nanotubes and ionic liquids (CNFs/SWCNTs/ILs) and examines the electrochemical and electromechanical properties of the CNF/SWCNT/IL gel hybrid actuators.
