中文摘要: 通过对碳纳米管薄膜进行重氮化处理,制备对氯苯胺修饰碳纳米管(D-CNT)薄膜,并以D-CNT薄膜为基底,在其上原位缩聚生长聚(2,5-二羟基-1,4-苯醌硫)(PDBS),构筑对氯苯胺修饰碳纳米管负载聚(2,5-二羟基-1,4-苯醌硫)(D-CNT@PDBS)柔性电极。研究发现,使用D-CNT薄膜作为基底,PDBS成功包覆到D-CNT上,D-CNT@PDBS柔性电极的面积比电容达到100.8 mF/cm2(当电流密度为1mA/cm2时),明显高于PDBS电极材料(65.59mF/cm2)和纯碳纳米管薄膜负载PDBS(CNT@PDBS)柔性电极(83.2 为柔性负极,与丙烯酸酯橡胶/四乙基四氟硼酸铵-乙腈准固态电解质(ACM/Et4NBF4-AN)匹配组装,得到柔性有机非对称超级电容器(D-CNT@PDBS//ACM/Et4NBF4-AN//CNT@PDAA),其能量密度达到1.63mWh/cm3(63.5 mW/cm3), 循环充放电8000次,电容保持率约为80%。

Abstract:P-chloroaniline modified carbon nanotube film (D-CNT) was prepared by diazotization reaction of carbon nanotube (CNT) film. Poly(2,5-dihydroxy-1,4-benzoquinonyl sulfide) (PDBS) was grown uniformly on the as-prepared D-CNT by in-situ polymerization method and D-CNT@PDBS flexible electrode was obtained. It was found that PDBS was coated on the D-CNT film successfully. The D-CNT@PDBS flexible electrode exhibited an area specific capacitance (CA) of 100.8 mF/cm2, higher than pure PDBS (65.59mF/cm2) and CNT-supported PDBS (CNT@PDBS, 83.2 mF/cm2). With the D-CNT@PDBS as flexible positive electrode, CNT supported poly (1, 5-diamino-anthraquinone) (CNT@PDDA) as flexible negative electrode, and crylic rubber cross-linked memberane/tetraethyl tetrafluorate acetonitrile electrolyte(ACM/Et4NBF4-AN) as the quasi-solid-state electrolyte, flexible D-CNT@PDBS//ACM/Et4NBF4-AN//CNT@PDAA organic asymmetric supercapacitor was assembled. The electrochemical results showed that energy density of the as-assembled flexible organic asymmetric supercapacitor was 1.63 mWh/m3 (63.5mW/ m3). After 10000 charging-discharging cycles, capacitance retention rate was 80%, confirming its excellent cycle performance.
