采用软化学合成法合成出基面间距为0.70nm的层状二氧化锰(bir-MnO2),并利用表面吸附技术制备了层状二氧化锰/苯胺-邻甲氧基苯胺共聚物复合材料(bir-MnO2/P(An-co-oAs)),借助FTIR、XRD、SEM、TGA、四探针和充放电循环实验等测试手段对样品的结构与性能进行表征.结果表明,P(An-co-oAs)的引入,对复合材料中bir-MnO2的层状结构破坏较小,P(An-co-oAs)通过氢键和静电作用吸附在bir-MnO2的表面.与bir-MnO2相比,复合材料的电导率提高2个数量级.首次放电比容量由bir-MnO2的188mAh/g提高到复合材料的202mAh/g.
