将海藻酸钠水溶液滴加到MnCl2水溶液中凝固成海藻酸锰小球。海藻酸锰小球吸附吡咯单体,在酸性KMnO4溶液中使吡咯单体氧化聚合成聚吡咯(PPy),得到聚吡咯/海藻酸锰复合小球(MPM)。用红外光谱仪、扫描电子显微镜和电化学工作站表征了复合小球的结构、形貌和电化学性能。结果表明:直径为200~500 nm的PPy微球聚集在海藻酸锰小球的表面。随着海藻酸钠在MnCl2水溶液的凝固时间增加,MPM的PPy含量偏低,复合小球的电容值减小。这种具有导电和生物相容性的MPM将在新型电极材料领域得到应用。
將海藻痠鈉水溶液滴加到MnCl2水溶液中凝固成海藻痠錳小毬。海藻痠錳小毬吸附吡咯單體,在痠性KMnO4溶液中使吡咯單體氧化聚閤成聚吡咯(PPy),得到聚吡咯/海藻痠錳複閤小毬(MPM)。用紅外光譜儀、掃描電子顯微鏡和電化學工作站錶徵瞭複閤小毬的結構、形貌和電化學性能。結果錶明:直徑為200~500 nm的PPy微毬聚集在海藻痠錳小毬的錶麵。隨著海藻痠鈉在MnCl2水溶液的凝固時間增加,MPM的PPy含量偏低,複閤小毬的電容值減小。這種具有導電和生物相容性的MPM將在新型電極材料領域得到應用。

Alginate mangane microspheres were prepared by dipping the alginate solution in the manganese chloride solution,and then used to adsorb the pyrrole monomer. Using acidic potassium permanganate solution as oxidation agent,the pyrrole monomer was polymerized to form the polypyr?role(PPy)on the surface of the alginate manganese spheres to form the composites microspheres of PPy/alginate manganese. The structure,morphology and electrochemical properties of the composite spheres were characterizated by the infrared spectroscopy,SEM and electrochemical workstation. The results showed that there was PPy microspheres with 200 to 500 nm diameter on the surface of the composites spheres of alginate manganese. As increasing the solidification time,PPy/alginate manganese alginate composite spheres had a tighter structure with a lower polypyrrole amount,its ca?pacitance decreased. Such spheres with the biocompatible and conduct properties will be widely ap?plied in the novel electrode field.
