中文摘要:
      通过加入十二烷基苯磺酸钠制备聚苯胺/聚乙烯醇/磺化石墨烯(PANI/PVA/S-GNS)导电复合材料,采用红外光谱、X射线衍射、扫描电子显微镜对其结构和形貌进行表征;通过溶解性能测试,表明十二烷基苯磺酸钠的加入,可有效降低PANI的团聚,提高复合材料的溶解性能;通过循环伏安和交流阻抗对其电化学性能进行测试,结果显示少量S-GNS的加入就能提高复合材料的电性能,在扫描速率为50 mV/s时,PANI/PVA/S-GNS的比电容为661.2 F/g,远大于比电容为354.3 F/g的PANI/PVA。
英文摘要:
      Polyaniline/poly (vinyl alcohol) /sulfonated graphene (PANI/PVA/S-GNS) conductive composites were prepared by the addition of sodium dodecylbenzenesulfonate and they were characterized via FT-IR, XRD and SEM. Through the test of the solubility, the results show that the addition of sodium dodecylbenzene sulfonate can effectively reduce the agglomeration of PANI and improve the solubility of the composites. The electrochemistry features of the composites were measured based on cyclic voltammetry (CV) and AC impedance. The results demonstrate that S-GNS as support material can improve the electrical properties of the composites. At a scanning rate of 50 mV/s, PANI/PVA/S-GNS shows a higher specific capacitance of 661.2 F/g compared with 354.3 F/g of PANI/PVA.
