【摘要】 采用双原位复合法,以(NH4)2S2O8和AgNO3两者为氧化剂共同氧化苯胺溶液,制得Ag/PANI。研究了(NH4)2S2O8和AgNO3两种氧化剂氧化苯胺的比例(P)以及HNO3浓度对Ag/PANI形貌以及电导率的影响。利用场发射扫描电镜(FE-SEM)、傅立叶红外光谱(FT-IR)以及四探针测试仪等手段,对Ag/PANI的形貌、结构及电导率进行了表征,结果表明,P为0.4,在1.0mol/L HNO3的溶液中氧化0.2mol/L的苯胺可得到均匀的棒状结构,且电导率较好,达10.2755S/cm。更多还原

【Abstract】 Polyaniline-silver complex was obtained by the double-situ composite method,which was polymerized via the oxidant of both ammonium persulfate and silver nitrate of aniline.Results showed that the ratio of ammonium persulfate to silver nitrate and the concentration of nitric acid had a great influence on morphology and the conductivity of silver/polyaniline materials.The morphology and structure of complex were characterized by scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FT-IR).Four-probe measurements was employed to investigate electrical conductivity.As 0.2mol/L aniline dissolved in 1.0mol/L nitric acid was polymerized via mixed oxidation with the ratio of 0.4,which could get the homogeneous rod structure and the conductivity of the pellet was up to 10.2755S/cm.更多还原
