Composites of LiMn_2O_4 and polypyrrole were successfully synthesized in nanotubules, and nanotubules composites were found to possess very high activities as the electrode materials for lithium secondary batteries.The nanotubule composite electrodes were prepared using a commercially available alumina membrane which has cylindical pores (200nm, diameter) of 20x10^<10> pores/cm^2 as a template. First, Li Mn_2O_4 was synthesized in the pores and then pyrrole was polymerized in the pores using the oxide as an oxidizing agent.The nanotubules composite of polypyrrole and LiMn_2O_4 showed the greater performances as a cathode active material for lithium secondary battery than that of a conbentional LiMn_2O_4 thin film. This enhanced performances was mostly indebted to a high specific surface area of the nanotubules electrode and to the function of polypyrrole as a conducting matrix. The effectiveness of this approach has been demonstrated also for other composites such as polyaniline and V_2O_5 and polythiophene and carbon.The nanotubules of polypyrrole was found to work as an excellent matrix for immobilizing enzymes at a high concentration. The array of nano-capsuled enzyme worked as a high-sensitive and-selective enzyme sensor.The conclusion is derived from this international joint project that the composites formation of conducting polymers with other materials such as metal oxides and enzymes is useful as the means of developing novel functions, and the nano-structuring of these composites is an effective way to enhance thir performance.

Limn_2O_4和多吡咯的复合材料在纳米管中成功合成，并且发现纳米管复合材料具有很高的活性，作为锂二级电池的电极材料。纳米管复合材料电极使用具有市售的Alumina Membrane cylindical cylindical pores（200n）（200n）（200n）（200n）（200n）（200n）（200n）制备。 ）为20x10^<10>孔/cm^2作为模板。首先，将li mn_2o_4合成在孔中，然后在孔中使用氧化物在孔中聚合作为氧化剂，在毛孔中聚合。多氧化醛的纳米管复合材料和limn_2o_4的纳米管表现出比乳头上的阴极活性材料更大的表现出更大的性能limn_2O_4薄膜。这种增强的性能主要欠纳米管电极的高比表面积和多吡咯的功能作为导电矩阵。对于其他复合材料，例如聚苯胺和V_2O_5，以及聚噻吩和碳的有效性。发现多吡咯的纳米管可作为固定酶以高浓度固定酶的极好基质。一系列纳米含有的酶是一种高敏感和选择性的酶传感器。该结论源自该国际关节项目，即与其他材料（例如金属氧化物和酶）形成的复合材料，例如金属氧化物和酶开发新型功能，这些复合材料的纳米结构是提高时期性能的有效方法。
