以便与高特定的电容和突出的 stretchability 开发优秀 pseudocapacitor 与在便携的未来和 bio-implantable 系统适用的另外的设备匹配,我们在三个重要方面上集中我们的研究:混合电影电极,在不同部件之间的接口,和在基于围单人赛的碳 nanotube/polyaniline (SWCNT/PANI ) 的 supercapacitors 的 stretchability 和电气化学的综合性能的 Stretchability 预先伸长的弹性体上的合成电影。由于中等的孔,弄弯的混合电影避免裂开它发生在常规可拉长的混合电极,和两个 435 F
In order to develop an excellent pseudocapacitor with both high specific capacitance and outstanding stretchability to match with other devices applicable in future wearable and bio-implantable systems, we focus our studies on three vital aspects: Stretchability of hybrid film electrodes, the interface between different components, and the integrated performance in stretchability and electrochemistry of supercapacitors based on single-walled carbon nanotube/ polyaniline (SWCNT/PANI) composite films on pre-elongated elastomers. Owing to the moderate porosity, the buckled hybrid film avoids the cracking which occurs in conventional stretchable hybrid electrodes, and both a high specific capacitance of 435 F.g-1 and a high strain tolerance of 140% have been achieved. The good SWCNT/PANI interfacial coupling and the reinforced solid electrolyte penetration structure enable the integrated pseudocapacitors to have stretch- resistant interfaces between different units and maintain a high performance under a stretching of 120% elongation, even after 1,000 cyclic elongations.
