Synthesis,Characterization and Electrochemistry of Conduting Polymer Polytripheylamine

Abstract

能源在人类的发展历史中发挥着重要的推动作用,是整个人类生存和发展的重要基础,化学电源是储存电能的最好设施。导电聚合物作为一种重要的电极材料,在电化学器件的发展应用中发挥重要作用,聚三苯胺(PTPAn)既具有类似聚对苯(PPP)的导电骨架,又具有聚苯胺(PAni)的单元结构,具备提供高的能量密度和功率密度的可能性。 本文通过化学方法合成了聚三苯胺材料,测试了其作为有机体系超级电容器正极材料的电化学性能;通过异相沉淀法制备了不同炭材料与聚三苯胺材料的复合物,测试了其作为有机体系超级电容器正极材料的电化学性能。将聚三苯胺材料作为锂离子电池正极材料的过充保护添加剂进行了研究。结果表明: 使用ClO...Super capacitors provide really high power density, while Li-ion batteries provide high energy density. Both of them are probably the most important next generation energy storage devices. Electroactive conducting polymers are a large family of the molecules capable of high-rate storage and delivery of power because of their high electronic conductivity and feasible rapid electrochemical kinetics...学位:理学硕士院系专业:化学化工学院化学系_物理化学(含化学物理)学号:2052007115097
