| Abstract:In this study, cellulose fibers (CFs) were mildly “etched” using cellulase to prepare modified cellulose fibers (m-CFs), followed by the fabrication of PANI/m-CFs paper-based electrode materials via in-situ oxidative polymerization of aniline (ANI) monomer. The results showed that m-CFs possessed a microscopic surface-roughened structure. Under optimized enzymatic conditions, the resulting electrode achieved a PANI loading of 2.93 mg/cm² and a resistivity of 0.113 kΩ·cm. When evaluated as supercapacitor electrodes, the charge transfer resistance decreased from 3.31 Ω (PANI/CFs) to 1.84 Ω (PANI/m-CFs), and the areal specific capacitance reached 2 098 mF/cm² at 1 mA/cm² of current density. Furthermore, the cycling stability improved from 73.6% to 78.9% after modification. These findings demonstrated that mild pretreatment with cellulase was a highly effective strategy for enhancing the electrochemical performance of cellulose-based electrode materials. |
