Abstract

The invention discloses a preparation method of a PEDOT high-conductivity flexible paper material, and belongs to the technical field of supercapacitor electrode materials. The preparation method comprises the steps of preparing an oxidant solution with a certain concentration, soaking a flexible substrate in the oxidant solution, taking out the flexible substrate, drying, and carrying out gas-phase polymerization in a sealed system; and washing and drying to obtain the PEDOT high-conductivity flexible paper material after the reaction is completed. The method is implemented by controlling polymerization of a solid-phase oxidant and an EDOT gas-phase interface on cellulose paper, the film has strong adhesion with a substrate, the flexibility of the cellulose paper is maintained, and the conductivity is stable. In addition, it is proved by practice that the method can be used for preparing 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...
