| 摘要:本研究利用纤维素酶在水浴条件下对纤维素纤维（CFs）表面进行温和“刻蚀”制备酶改性纤维素纤维（m-CFs）；并利用m-CFs和苯胺（ANI）单体通过原位氧化聚合法制备PANI/m-CFs电极材料。结果表明，m-CFs纤维具有微观表面粗糙结构，优化后的酶处理工艺使电极材料的负载量和电阻率分别达2.93 mg/cm²和0.113 kΩ·cm，将其作为超级电容器的电极，电荷转移阻抗由3.31 Ω（PANI/CFs）降低至1.84 Ω（PANI/m-CFs），面积比电容达2 098 mF/cm²（在1 mA/cm²电流密度下），电极材料的循环稳定性由73.6%（PANI/CFs）提升至78.9%（PANI/m-CFs），证明了纤维素酶温和预处理是改善纤维素基电极材料性能的有效方法。 |
| 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. |
