摘要
以原位聚合法制备了导电聚合物聚苯胺/聚3,4-乙烯二氧噻吩(PANI/PEDOT)复合阳极材料.研究了复合乳化剂浓度对PANI/PEDOT复合阳极材料的电化学性能和结构的影响.用线性扫描、交流阻抗、傅里叶变换红外光谱和X-射线衍射对所得的复合阳极材料的电化学特性、物相和结构进行了表征.结果表明,当复合乳化剂浓度为0.2mol/L时,PANI/PEDOT复合阳极材料具有较好的导电性,所得复合材料的分子链有序性较好,结构规整,结晶性好.
Conducting polyaniline （ PANI ）/poly （ 3,4 - ethylene dioxythiophene ） （PEDOT） anodes is prepared by in - situ polymerization. The influences of different concentrations of composite emulsifiers on the electro- chemical performance and structure of anodes are investigated thereafter. The electrochemical performance, structure and crystallinity of synthesized materials are then characterized by means of linear sweep voltammetry, electrochemical impedance spectroscopy, Fourier transform infrared spectroscopy and X - ray diffraction. The results show that the higher conductivity composite can be obtained at 0.2mol/L of mulriple emulsifiers, that the chain of PANI/PEDOT is more ordered, and that the crystallinity is higher than that of PANI.
