A Study on Conducting Polymers and Its Power Application

制备了具有高共轭电子系统的导电聚合物，用于导体和二次电池等电源应用。结果总结如下：1。采用化学法、电化学法和前驱体膜热处理法制备了聚（噻吩）、聚（对苯乙烯）及其衍生物聚（3-烷基噻吩）和聚（2,5-二氧基-对苯乙烯）。这些导电聚合物的电子性质取决于其取代基的结构。这些发现为设计一种具有低自放电率和高稳定性的电极活性材料提供了依据。这些导电聚合物的掺杂行为取决于制备方法。从掺杂扩散速率随导电聚合物形态变化的角度解释了这种依赖关系。发现导电聚合物的一阶和高阶结构影响掺杂（金属）态的稳定性。以含氧烃类化合物为原料，在红外辐射下，用CVD法制备了石墨膜。在FeCl_3和k - 6的插层状态下，石墨薄膜的金属电导率高达10^5 S/cm。-高导电性（掺杂）态的稳定对于作为导体的实际应用具有重要意义。

Conducting polymers having highly conjugated electron system were prepared for use in power application such as conductor and secondary battery. The Results were summarized as follows.1. Poly(thiophene), Poly(p-phenylenevinylene) and its derivatives such as poly(3-alkylthiophene) and poly(2,5-diethoxy-p-phenylenevinylene) were prepared by chemical method, electrochemical method and heat-treatment of precursor film.2. Electronic properties of these conducting polymers depended on structure of its substituent group. These findings allow to design a electrode active material having low self discharge rate and high stability.3. Doping behavior of these conducting polymers depended upon preparation method. Such the dependency is explained from term of change of diffusion rate of dopnat ion depending on morphorogy of the conducting polymers.4. It was found that the first and higher order structure of the conducting polymers affect stability of doped(metallic) state.5. Graphite films were obtained by CVD method under infla-red irradiation from oxygen-containing hydrocarbon compounds. The resulting graphite films showed metallic conductivity as high as 10^5 S/cm in its intercalated state with FeCl_3 and K.6.- It was also concluded that stabilization of highly conductive (doped) state is important to practical application as conductors.
