【摘要】：导电聚合物既具有类似金属的电学性质，又具备有机聚合物的柔性和机械性能，因此引起了科研工作者的广泛关注。具有纳米结构的导电聚合物在多方面性质上均优于宏观块体材料；而且通过不同的纳米结构的设计与调控，导电聚合物的性质也可发生大幅变化。导电聚合物易于修饰与复合，可以直接与二维纳米材料及其他功能纳米材料形成复合物；而且通过不同的制备方法，所制备的复合物由于各组分之间的相互作用不同，也具有不同的性质。在本论文中，我们通过不同的合成方法，制备了几种新型导电聚合物微纳米结构材料及其与二维纳米材料的复合物。主要包括以下三部分内容：（1）为了研究不同微纳米结构对导电聚合物膜表面浸润性质的影响，制备了两种具有不同微纳米结构的聚吡咯膜材料，对比了两种微纳米结构对聚吡咯膜表面亲疏水性质的影响，并期待其在吸油和油水分离性质上取得良好应用。（2）通过水热合成法制备聚吡咯与二硫化钼纳米片复合物，并进一步通过自组装法制备了MoS2/PEDOT/Pd三元复合物，研究了在各组分间的协同作用下复合物的类过氧化物酶催化性质。（3）采用二硫化钼或还原氧化石墨烯为包覆材料，通过水热合成法制备了具有核壳结构的二维纳米片包覆的聚苯胺纳米纤维多级结构，，并研究了这种核壳结构对于复合物在电化学电容器中循环稳定性的影响。
[Abstract]:The conductive polymer has electrical properties similar to metal, but also have the flexibility of organic polymer and mechanical properties, it has aroused widespread concern of researchers. The conductive polymer with nano structure in many aspects of nature are better than bulk materials; and through the design and control of nano structure with the properties of conductive polymers is also can changes. Easy modification and composite conductive polymer, can form complexes with two-dimensional nano materials and other functional materials; and by different preparation methods, the prepared complexes due to the interaction between the components is different, also has different properties. In this paper, we synthesized by different methods of preparation of several novel conductive polymer composite and micro nano structure materials with two-dimensional nano materials mainly include the following three parts. Content: (1) in order to study the influence of different micro nano structure on the conductive polymer film surface wetting properties, preparation of two kinds of materials with different PPy film micro nano structure, the effect of two kinds of micro nano structure on the surface hydrophobic properties of polypyrrole films were compared, and look forward to its good application in oil and water separation nature. (2) the preparation of polypyrrole and Molybdenum Disulfide Composites by hydrothermal synthesis method, and further prepared by the self-assembly of MoS2/PEDOT/Pd three ternary complexes were studied in the class of peroxidase complex catalytic properties of the synergistic effect between different components. (3) using molybdenum disulfide or reduced graphene oxide for the coating material, with core-shell structure nanosheets coated with polyaniline nanofibers were prepared by multistage structure hydrothermal synthesis method, and studied the core-shell structure for complexes in electrochemical The influence of the cycle stability in the capacitor.
