中文摘要:
      目的 以甲壳素纳米纤维、多壁碳纳米管、碳布、吡咯为原料,制备柔性超级电容器复合电极薄膜。方法 先利用化学氧化法提高碳布的表面粗糙度,再通过真空抽滤在碳布表面附着甲壳素纳米纤维和多壁碳纳米管,以增加碳布的负载空间,最后通过原位聚合吡咯来增加复合薄膜的电容性能。同时制备氧化碳布/聚吡咯复合薄膜作为对照组。结果 制成的氧化碳布/甲壳素纳米纤维/多壁碳纳米管/聚吡咯复合薄膜在扫描速率为5 mV/s时,质量比电容达到了307 F/g,是氧化碳布/聚吡咯质量比电容(175 F/g)的1.75倍;在电流密度为2 A/g时,经过2000次循环后电容保留率为72.3%,库仑效率为73.8%。结论 制备的氧化碳布/甲壳素纳米纤维/多壁碳纳米管/聚吡咯薄膜具有较高的比电容和循环稳定性,可以作为超级电容器电极材料应用于物联网行业的有源储能包装。
英文摘要:
      The paper aims to prepare flexible electrode film for supercapacitor with untreated carbon cloth (UCC), chitin nanofibers (ChNFs), multi-wall carbon nanotube (MWCNTs) and pyrrole (Py) as raw materials. Firstly, the surface roughness of carbon cloth was improved through chemical oxidation. Then, ChNFs/MWCNTs were attached on the surface of OCC by vacuum-filtration process to increase the load space of the carbon cloth. Finally, the capacitive performance of the composite film was increased through in situ polypyrrole (PPy). Meanwhile, OCC and PPy composite films were prepared for comparison. The specific capacitance of OCC/ChNFs/MWCNTs/PPy film reached 307 F/g, which was 1.75 times of the specific capacitance of OCC/PPy (175 F/g) at the scan rate of 5 mV/s. Moreover, OCC/ChNFs/ MWCNTs/PPy film had good cycling stability with the capacitance retention of 72.3% and coulombic efficiency of 73.8% after 2000 cycles at the current density of 2 A/g. This high-performance OCC/ChNFs/MWCNTs/PPy film has high specific capacitance and cycling stability. It could be regarded as trackable package in Internet of Things.
