摘要： 以RuCl3.nH2O为原料通过溶胶-水热法制得纳米RuO2粒子,然后在RuO2溶胶体系中通过常规的化学氧化法由苯胺氧化聚合制备纳米RuO2/聚苯胺复合材料,采用扫描电镜(SEM)和X-射线衍射(XRD)对其形貌和微观结构进行表征,并用循环伏安法研究了不同RuO2质量分数的复合材料电极的电化学性能。结果表明,RuO2质量分数为5%时,RuO2/聚苯胺复合材料形成致密的表面包覆型结构,聚苯胺电化学电容消失,复合材料电极电容很小。RuO2质量分数大于或小于5%时,RuO2粒子呈弥散状分布在聚苯胺中;RuO2质量分数为3%时,复合材料比电容达到极值374.6 F/g,这种复合材料具有很好的电化学特性,适于用作超级电容器电极。

Abstract: Nanometer RuO2 particle were prepared by sol-hydrothermally method using RuCl3·nH2O as raw material,and RuO2 /polyaniline composite were fabricated from aniline polymerization in RuO2 sol by conventional chemical oxidation.The morphology and microstructure were characterized by SEM and XRD,and its electrochemical properties were investigated with cyclic voltammetry.The results indicate that the structure of the composites vary by different mass fraction of RuO2.When the mass fraction of RuO2 is 5%,compact RuO2 coats are formed on the surface of polyaniline particles,and electrochemical capacitance of the composite diminish due to polyaniline capacitance disappearance.RuO2 particles are dispersed in the polyaniline when the mass fraction of RuO2 is more or less than 5%.The capacitance of the composite reaches the maximum is 374.6 F/g when the RuO2 mass fraction is 3%.The composite with less RuO2 content has good electrochemical property which is suitable for supercapacitors.
