The method comprises sensitizing apolyester fiber fabric and a yarn for an ordinary textile with stannous chloride, preparing a fabric / carbon nano tube fabric electrode and a yarn / carbon nano tube yarn electrode, preparing a conductive polymer / fabric / carbon nano tube fabric electrode and a conductive polymer / yarn / carbon nano tube yarn electrode and applying the same to a flexible super capacitor. The method of the invention has the advantages of simple process, low cost and universal applicability. The planar and fiber-type symmetric super capacitors in which the fabric electrode and the yarn electrode are assembled also achieve excellent electrochemical performance.

Description

technical field [0001] The invention relates to a preparation method of a carbon nanotube fabric electrode and a yarn electrode and an application of the electrode. Background technique [0002] At present, with the development of portable and wearable electronic products, high-performance flexible electrodes have become an important research direction in the field of energy storage. Ordinary textile fabrics have mature preparation technology, can be produced on a large scale, and have abundant sources of raw materials; textile fabrics have a three-dimensional porous network structure, making them extremely flexible; textile fabrics have good air permeability. However, fabrics for textiles are not conductive and cannot be directly used as electrodes, so conductive treatment is required. Carbon nanotubes have high conductivity and large specific surface area, and the flexible electrode formed by compounding them on the surface of the fabric has both the advantages of fabric ...
