The molecular interactions in SWCNT/conducting polymer composites and their influence on the doped state of these components is the main focus of the present research proposal. For this purpose model structures like SWCNT of different diameters and conduction mechanism on the carbon side and aniline oligomers and polymers on the polymer side are used to understand the doping of each component in a composite and the influence of the doping on the type and extension of the interaction of the components. Experimentally the study is preferably done by electrochemical and in situ ESR-UV-Vis-NIR spectroelectrochemistry to get a detailed information of the charged states of the organic structures of aniline oligomers and polymers like cation radicals, dications, polarons, bipolarons and polaron pairs. Using the in situ ESR-UV-Vis- NIR spectroelectrochemical methods we want to obtain selective information on the type and the equilibria of the doped states in the organic structure. Thus the conduction mechanisms of such composites can be interpreted.

SWCNT/导电聚合物复合材料中的分子相互作用及其对这些组分掺杂状态的影响是本研究的重点。为此，我们使用碳侧不同直径和导电机理的单壁碳纳米管和聚合物侧的苯胺齐聚物和聚合物等模型结构来了解复合材料中各组分的掺杂情况，以及掺杂对各组分相互作用类型和程度的影响。实验上，采用电化学和原位ESR-UV-VIS-NIR光谱电化学法对苯胺齐聚物和聚合物(如阳离子自由基、阳离子、极化子、双极化子和极化子对)的有机结构的带电状态进行了详细的研究。利用原位ESR-UV-VIS-NIR光谱电化学方法，我们希望获得关于有机结构中掺杂态的类型和平衡的选择性信息。从而可以解释这种复合材料的导电机理。
