柔性自支撑介孔碳纳米纤维的制备及其在超级电容器电极上的应用
Preparation of flexible free-standing mesoporous carbon nanofibers and its application in electrodes for supercapacitor
摘要
Abstract
In order to prepare the flexible mesoporous carbon nanofibers, which is used as free-standing supercapacitor material, a novel type of one -dimensional mesoporous carbon nanofibers has been prepared via the electrospinning technique and thermal treatment by using resol as the carbon source and triblock copolymer Pluronic F127 as the template.The mesoporous carbon nanofibers are characterized by x-ray diffraction,specific surface area and pore distribution.The results show that there are a lot of mesoporous structures in the carbon nanofibers with addition of Pluronic F127. The obtained MCNFs-2 shows a mesoporous structure with ultra-high specific surface area of 1 444.26 m2/g, providing numerous electroactive sites to accommodate more charges.As a result,the MCNFs-2 electrode exhibites high specific capacitance(139.6 F/g at 0.05 A/g)and excellent rate of performance in a 6 mol/L KOH aqueous solution.关键词
