将苯胺单体引入无烟煤的微纳米孔隙及芳香层片中,原位聚合制备出含微纳米结构特征的无烟煤/聚苯胺复合材料,其电导率稳定在101S·m-1数量级。并分别用SEM、FTIR电阻仪和电化学工作站对其结构和性能进行了表征,结果发现:无烟煤与聚苯胺间发生了较强的化学键合和氢键结合。当无烟煤/苯胺质量配比为1/2时,得到的复合材料电导率最高,为72.5S·m-1,制作的电极比电容为84.5F/g,且兼有赝电容和双电层电容特征。
The aniline monomer was introduced into the micro-nano pores and the aromatic layer of the anthracite, and the anthracite / polyaniline composite material with the micro-nano structure was prepared by in-situ polymerization. The conductivity was stable at the order of 101S · m-1. Their structures and properties were characterized by SEM, FTIR and electrochemical workstation respectively. The results showed that strong chemical bonding and hydrogen bonding occurred between anthracite and polyaniline. When the mass ratio of anthracite to aniline is 1/2, the composite obtained has the highest conductivity of 72.5S · m-1, the specific capacitance of the electrode is 84.5F / g, and the pseudocapacitance and electric double layer capacitance feature.
