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.

在纳米管中成功地合成了LiMn_2O_4与聚吡咯的复合材料，并发现纳米管复合材料作为锂二次电池电极材料具有很高的活性。纳米管复合电极的制备采用市售的氧化铝膜为模板，该膜具有20 × 10^<10>孔/cm^2的圆柱形孔（200nm，直径）。首先在孔隙中合成Li Mn_2O_4，然后以氧化物为氧化剂在孔隙中聚合吡咯。聚吡咯- LiMn_2O_4纳米管复合材料作为锂二次电池正极活性材料的性能优于传统的LiMn_2O_4薄膜。这种增强的性能主要归功于纳米管电极的高比表面积和聚吡咯作为导电基质的功能。这种方法的有效性也被证明是其他复合材料，如聚苯胺和V_2O_5和聚噻吩和碳。聚吡咯纳米管是一种高浓度固定酶的优良基质。该纳米胶囊酶阵列是一种高灵敏度、高选择性的酶传感器。该国际合作项目的结论是，导电聚合物与金属氧化物、酶等材料形成复合材料是开发新功能的有效手段，而纳米结构是提高其性能的有效途径。
