以生物制剂肝素钠为掺杂剂,由自组装方法合成出平均粒径为100 nm的球状聚吡咯(PPy),用作超级电容器电极材料.透射电镜(TEM)、循环伏安、恒流充放电和电化学交流阻抗测试表明,肝素钠掺杂聚吡咯呈现较好的形貌和电容性质,在电流密度3 mA/cm2下充放电,单电极比电容达到338 F/g. ; Spherical-like polypyrrole with an average diameter of 100 nm as the electrode material for supercapacitor was prepared by a self-assembly process with heparin sodium salt as the dopant at-10 ℃.The morphology and electrochemical properties were characterized by transmission electron microscopy(TEM),cyclic voltammetry(CV),galvanostatic charge/discharge and electrochemical impedance spectroscopy(EIS) measurements.The results showed that the polypyrrole doped with heparin sodium salt exhibited good capacitive behavior.The specific capacitance of single electrode was up to 338 F/g at 3 mA/cm2. ; 作者联系地址：新疆大学应用化学研究所,南京航空航天大学材料科学与技术学院,新疆大学应用化学研究所,新疆大学应用化学研究所 新疆乌鲁木齐830046,西安交通大学理学院,陕西西安710049,江苏南京210016,新疆乌鲁木齐830046,新疆乌鲁木齐830046 ; Author's Address: 1.Institute of Applied Chemistry,Xinjiang University,Urumuqi 830046,Xinjiang,China;2.College Science of Jiaotong University Xi'an,Xi'an 710049,Shanxi,China;3.College of MaterialScience & Engineering,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,Jiangsu,China
