摘　　要：采用杂多酸H3PMo12O40为氧化剂和掺杂剂，化学氧化法制备掺杂态聚吡啶．用红外光谱、扫描电镜等手段表征产物的结构和微观形貌，并研究掺杂态聚吡啶的循环伏安特性和热稳定性．结果表明，制备的掺杂态聚吡啶形貌为0．1～0．6μm的不规则颗粒，能表现出杂多酸和掺杂态聚吡啶的电化学行为，并具有一定的热稳定性，聚吡啶在511℃以上分解失重．Polypyridine was prepared by means of chemical oxidation with H3PMo12O40 as oxidant and dopant. The structure and microscopic morphology of the product polypyridine were characterized with FT-IR and SEM, and its electrochemical performance was studied, also. The result showed that the prepared doped polypyridine was irregular granule with 0. 1-0. 6 μm granularity. The electrochemical performance of H3PMo12O40 and polypyridine could be manifested. The product possessed definite thermosta- bility. Polypyridine was decompounded at temperature above 511 ℃.
