Problems solved by technology

For example, Uetani et al. used electrostatic flocking to vertically place carbon fibers on the surface of polyimide films, and at the same time pour resin materials between the fibers to prepare high-performance heat-insulating films. The method is simple and can quickly prepare large-area vertical load materials, but At present, the application in the construction of three-dimensional flexible conductive materials is still blank

Description

technical field [0001] The invention belongs to the field of electrochemical materials, in particular to a preparation method of a three-dimensional aminated carbon nanotube array / stretchable textile fiber electrode material. Background technique [0002] As an emerging energy storage device, supercapacitor has the characteristics of high power density, short charging time, high cycle performance and energy saving, and has received extensive attention in the field of thin, flexible and wearable power supplies. Although supercapacitors have certain flexibility, they basically do not have stretchability, that is, they cannot achieve large deformations similar to textiles under small stresses, which greatly limits their use in wearable medical monitoring, communication equipment or other small electronic products. Applications. Therefore, it is an important task to realize large-scale and low-cost fabrication of flexible capacitors with high energy density. [0003] Electrode...
