Abstract

The invention discloses a preparation method of a PEDOT high-conductivity flexible paper material, which belongs to the technical field of supercapacitor electrode materials, and comprises the following steps: preparing a certain concentration of oxidizing agent solution, soaking the flexible substrate in the oxidizing agent solution, taking it out and drying it, and Gas-phase polymerization is carried out in a sealed system; after the reaction is completed, the PEDOT highly conductive flexible paper material is obtained by washing and drying. Realized by manipulating the polymerization of the solid-phase oxidant on the cellulose paper and the EDOT gas-phase interface, the film has strong adhesion to the substrate, maintains the flexibility of the cellulose paper, and has stable electrical conductivity. In addition, it has been proved that this method can prepare large-area electrodes.

Description

technical field [0001] The invention belongs to the technical field of supercapacitor electrode materials, and in particular relates to a preparation method of a PEDOT high-conductivity flexible paper material. Background technique [0002] In energy management equipment, future lightweight electronics and electronics require flexibility while also reducing weight. Flexible energy storage systems require materials that are lightweight, stable, and can be integrated with other energy harvesting devices. Among the various existing energy storage devices, flexible supercapacitors are a very attractive and potential energy storage due to their advantages such as high power density, extremely long cycle life, Coulombic efficiency and wide range of temperature tolerance. equipment, has a wide range of application prospects. [0003] However, the bulk and lack of flexibility of current commercial supercapacitors limit their integration into devices. The exchange of individual cr...
