Description

technical field [0001] The invention relates to a preparation method of a polyaniline / stretchable fabric electrode material, the obtained material and its application, and belongs to the technical field of electrode material preparation. Background technique [0002] Compared with the previous rigid electrode materials, flexible electrodes have attracted more and more attention because of their softness and flexibility. Especially in wearable electronic devices, flexible electrodes have great application prospects. If human limb extension and daily activities are taken into consideration, endowing electrode materials in wearable devices with certain stretch properties will expand their practical application range. [0003] In order to achieve the stretchability of electrode materials, some researchers combine conductive materials with elastic substrates, usually film-like polydimethylsiloxane (PDMS), silicone or polyurethane. The patent "application number: 201510673308.7" ...
