摘要:纳米纤维素机械强度高、密度低且表面含有可化学改性的羟基官能团,可作为组装高性能超级电容器电极的优选材料。本文综述了纳米纤维素与导电聚合物、过渡金属氧化物等活性材料制备超级电容器软材料和碳基复合电极的机理,对冷冻干燥、碳化、原位聚合、过滤、涂覆等组装方法进行了详细讨论,并对纳米纤维素基电极的机械性能和电化学性能进行了对比和分析。最后,对纳米纤维素基电极在超级电容器中的应用前景进行了展望。
Abstract:Nanocellulose exhibits the high mechanical strength, low density, and has many chemically modified hydroxyl functional groups on its surface. Therefore, it becomes the ideal material for assembling high-performance supercapacitor electrodes. In this review, the main mechanisms of soft material and carbon-based composite electrodes prepared by using nanocellulose combined with some active materials, such as conductive polymer and transition metal oxide, etc., were introduced. Then the assembling methods including the freeze drying, carbonization, in situ polymerization, filtration and coating, were discussed in detail. In addition, the mechanical and electrochemical performances of nanocellulose-based supercapacitor electrodes were compared and analyzed. Finally, the potential application of nanocellulose-based electrodes in supercapacitors were prospected.
