摘要:本研究通过交替抽滤成膜的方法，以不同长度的TEMPO氧化纤维素纳米纤维（TOCNF）为原料，掺入还原氧化石墨烯（rGO），并引入导电聚苯胺（PANI），制备了包含rGO和PANI的纳米纤维素基复合材料（CNF&rGO@PANI）。通过调整rGO用量以及苯胺用量获得电化学性能优异的CNF&rGO@PANI，并对其进行了表征。结果表明，制备的CNF&rGO@PANI具有优异的电化学性能：比电容为213.21 mF/cm2，能量密度为106.6 mWh/cm2。
Abstract:In this study, TEMPO-oxidized cellulose nanofibers (TOCNF) with different lengths was used as the raw material. Reduced graphene oxide (rGO) was incorporated and conductive polyaniline (PANI) was introduced to fabricate nanocellulose-based composites containing rGO and PANI (CNF&rGO@PANI) via alternative vacuum filtration. CNF&rGO@PANI with outstanding electrochemical properties were obtained by adjusting the dosages of rGO and aniline, and the as-prepared materials were characterized. The CNF&rGO@PANI exhibited excellent electrochemical performance: the specific capacitance was 213.21 mF/cm², and the energy density was 106.6 mWh/cm². The obtained materials could be applied to the design and development of nanocellulose-based composites and new energy-related fields.
