The electronic interactions of SWCNT and conducting polymers in nanotube/polymer composites

swcnts /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主要重点。为此，使用不同直径的swcnts模型结构和碳侧的传导机制以及聚合物侧的苯胺低聚物和聚合物来了解复合材料中各组分的掺杂以及掺杂对组分相互作用类型和扩展的影响。实验研究最好通过电化学和原位ESR-UV-Vis-NIR光谱电化学来获得苯胺低聚物和聚合物的有机结构的带电状态的详细信息，如阳离子自由基，指示，极化子，双极化子和极化子对。利用原位ESR-UV-Vis- NIR光谱电化学方法，我们希望获得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传导机理。

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.
