    Preparation and Supercapacitive Performance of Polyaniline with MnO2 as Oxidant

    • 摘要: 以二氧化锰为氧化剂在酸水体系中化学氧化制备了聚苯胺(PANI),考察了聚合条件对产率的影响。采用红外光谱、扫描电镜等手段对PANI的结构与形貌进行了表征,采用电化学工作站对其电化学电容性能进行了测试。结果表明:PANI产率随着体系中氧化剂用量的增加、苯胺用量的减少、反应温度的降低和反应时间的延长而增加,制备的聚苯胺主要是翡翠亚胺型聚苯胺,并以颗粒形式存在,大小在100 nm左右,局部有团聚现象,颗粒间堆积蓬松;该聚苯胺作为超级电容器活性电极材料,具有较好的电化学电容性能,最高比电容达到178 F/g。

       

      Abstract: The doped polyainiline(PANI) was successfully polymerized with HCl as dopant and MnO2 as oxidant and characterized by scanning electron microscopy, filtergrating infrared spectrometer for structure and electrochemical station for supercapacitive performance. Results indicate that the monomer conversion is enhanced with the increasing of MnO2 concentration, the decreasing of monomer concentration, the falling of polymerization temperature and the extending of polymerization time. The prepared polyaniline is accumulated with shaggy grain which is about 100 nm, and shows excellent supercapacitive performance with a maximum specific capacitance of 178 F/g.
