以ITO导电玻璃为工作电极,在三电极系统中,采用循环伏安法制得聚苯胺薄膜,聚苯胺/铁氰化铜(CuHCF),聚苯胺/铁氰化钴(CoHCF),聚苯胺/铁氰化铈(CeHCF)复合材料。通过利用C-V、SEM、EDS、XRD、FT-IR等方法对导电复合物进行表征和性能研究。实验结果表明,制备复合物的最佳电解液浓度为0.02mol/L苯胺+0.002mol/L金属离子+0.01mol/L铁氰化钾+0.5mol/L H2SO4;聚苯胺与铁氰化物很好地键合在一起,聚苯胺/铁氰化钴复合材料的电化学性有进一步的提高,具有纳米粒子特性和独特的片状粒子结构;而聚苯胺/铁氰化铜和聚苯胺/铁氰化铈的电化学性能高于聚苯胺本体,粒子间有较大的空穴现象。
Polyaniline(PAni),polyaniline/copper hexacyanoferrate(CuHCF) and polyaniline/cobalt hexacyanoferrate(CoHCF),polyaniline/cerium hexacyanoferrate(CeHCF) films were synthesized using the cyclic voltammetry method(C-V) in electrolyte solution.In three electrode systems,the work electrode was the indium-tin-oxide(ITO) glass plate electrode,the electrochemical synthesis potential was in-0.3-1.1V and the scan rate of the system was 50mV/s.And then these films were characterized by C-V,FT-IR,TEM,XRD,EDS.These results showed that the best thickness of electrolyte solution was(0.02mol/L Ani+0.002mol/L metal ion+0.01mol/L K3Fe(CN)6+0.5mol/L H2SO4).Polyaniline and hexacyanoferrate were bonded together,so that the nature of polyaniline/MHCF have further improved.The micromor-phologies of PAni/CoHCF film was schistose and the electrochemical activity was the same as polyaniline.The particle size of PAni/CuHCF and PAni/CeHCF films was nanometer size and there were more cavitations.The electrochemical activity is better than PAni/CoHCF.
