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

Abstract

The invention relates to a preparation method for a three-dimensional aminated carbon nonotube array / stretchable textile fiber electrode material. The preparation method comprises the following steps of placing textile fiber subjected to pre-treatment in a composite agent containing a dispersing agent and an aminated carbon nanotube in a room temperature, carrying out immersion and drying to obtain a conductive and stretchable textile substrate; placing the aminated carbon nanotube in an electricity processing liquid to obtain aminated carbon nanotube subjected to electricity processing; and uniformly coating the conductive and stretchable textile substrate with a graphene conductive adhesive, implanting the aminated carbon nanotube subjected to electricity processing into the surface of the substrate through single-surface static electricity to obtain the three-dimensional conductive electrode material, carrying out pre-baking and baking, and absorbing the aminated carbon nanotube floated on the surface to obtain the three-dimensional aminated carbon nanotube array / stretchable textile fiber electrode material. The method disclosed by the invention is simple in process, the cost can be substantially reduced, and meanwhile, mass production of a high-capacitance electrode is achieved.

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...
