以石墨烯纳米片为骨架,聚吡咯为碳源,设计构建氮掺杂碳纤维包覆石墨烯纳米片(NFGNs)复合材料。采用SEM,XRD,Raman,FTIR,XPS和BET对材料进行表征,结果表明:相互连通的氮掺杂碳纳米纤维均匀地包覆生长在石墨烯纳米片层表面;NFGNs-800复合材料的氮原子分数为11.53%,比表面积为477.65 m~2·g~(-1)。电容特性测试结果表明:NFGNs-800电极材料的比电容为323.3F·g~(-1)(1.0A·g~(-1)),且具有良好的倍率特性;NFGNs-800超级电容器在功率密度为10500W·kg~(-1)时,能量密度为87.1Wh·kg~(-1);经过10000次恒流充放电循环后,比电容保持率95.9%,库仑效率保持在99%以上。 |

The N-doped carbon nanofiber coated graphene nanosheets(NFGNs)were designed and constructed using EGNs as the skeleton and PPy as the carbon source.The samples were characterized by SEM,XRD,Raman,FTIR,XPS and BET.The results show that the interconnected N-doped carbon nanofibers are uniformly coated on the surface of EGNs.The NFGNs-800 presents high-level nitrogen atom doping of 11.53%and large specific surface area of 477.65 m~2·g~(-1).The capacitance performance test results show that the NFGNs-800 electrode material exhibits high specific capacitance of 323.3F·g~(-1)(1.0A·g~(-1))and good rate characteristic.NFGNs-800 supercapacitor shows high energy density of 87.1 Wh·kg~(-1)at power density of 10500 W·kg~(-1).The specific capacitance of the supercapacitor is 95.9%of the initial specific capacitance and the columbic efficiency still remains above 99%after 10000 constant current charge discharge cycles. |
