Polymer grafting from graphitic carbon materials has been pursued for several decades. Unfortunately, currently available methods mostly rely on the harsh chemical treatment of graphitic carbons which causes severe degradation of chemical structure and material properties. A straightforward growth of polyaniline chain from the nitrogen (N)-doped sites of carbon nanotubes (CNTs) is presented. N-doping sites along the CNT wall nucleate the polymerization of aniline, which generates seamless hybrids consisting of polyaniline directly grafted onto the CNT walls. The resultant materials exhibit excellent synergistic electrochemical performance, and can be employed for charge collectors of supercapacitors. This approach introduces an efficient route to hybrid systems consisting of conducting polymers directly grafted from graphitic dopant sites.
几十年来，人们一直在研究从石墨碳材料上进行聚合物接枝。遗憾的是，目前可用的方法大多依赖于对石墨碳的苛刻化学处理，这会导致化学结构和材料性能的严重退化。本文提出了一种从氮（N）掺杂的碳纳米管（CNT）位点上直接生长聚苯胺链的方法。CNT 壁上的 N 掺杂位点引发苯胺聚合，生成由聚苯胺直接接枝到 CNT 壁上的无缝杂化材料。所得材料表现出优异的协同电化学性能，可用于超级电容器的集电器。该方法为直接从石墨掺杂剂位点接枝的导电聚合物的混合体系引入了一种有效的途径。
