摘要:本研究利用茜素红S掺杂调控聚苯胺层，以获得高性能纤维素纸基电极材料，并对其结构组成及性能进行研究。结果表明，茜素红S掺杂提高了聚苯胺颗粒的多孔性和负载量，从而提高了聚苯胺/纤维素纸基电极材料的热稳定性、导电性能和电化学性能。电化学测试表明，在电流密度为1 mA/cm²时，纸基电极材料的面积比电容为1960 mF/cm²，高于以往的研究。本研究为利用传统造纸工艺开发高性能、廉价、绿色的纸基功能材料提供了新的参考。

Abstract:In this study， alizarin red S doping was utilized to modulate the polyaniline layer in order to obtain high-performance paper-based electrode materials， as well as its structural composition and properties were investigated. The results showed that the doping of alizarin red S to polyaniline increased the porosity and mass loading of the polyaniline， which enhanced the thermal stability， electrical conductivity and electrochemical performance of the polyaniline/cellulose composite paper-based electrode materials. In addition， the electrochemical tests showed that the area specific capacitance of the paper-based electrode material was 1960 mF/cm² when the current density was 1 mA/cm²， which was higher than the previous studies. This study provided a new strategy for the development of high-performance， inexpensive， and green flexible electrode materials in traditional papermaking processes.
