摘　　要：采用简单易制的1-丁基-3-甲基咪唑氯盐作为离子液体,纳米Fe_3O_4作为胶凝剂制备准固态电解质。用油酸钾对纳米Fe_3O_4进行改性,考察纳米Fe_3O_4改性前后、不同质量比纳米Fe_3O_4对准固态电解质的影响。利用X射线衍射仪、扫描电子显微镜、傅里叶红外光谱仪、电化学工作站等对样品进行表征。结果表明,纳米Fe_3O_4改性后导致准固态电解质的电导率下降,当纳米Fe_3O_4含量为4%时,电导率最高;当纳米Fe_3O_4含量为12%时,I_3^-在Pt电极上的还原速度最快。The quasi-solid electrolyte has been prepared by the simple and easy 1-butyl-3-methylimidazolium chloride as ionic liquids and nano-Fe3O4 as gelator.Nano-Fe3O4 was modified with potassium oleate,investigating the modified and unmodified nano-Fe3O4,different ratios nano-Fe3O4 on the influence of the quasi-solid electrolyte.The samples were characterized by X-ray diffraction,scanning electron microscope, FTIR spectrometer,electrochemical workstation,etc.Results shown that the modified nano-Fe3O4 resulted in the decrease of conductivity.When nano-Fe3O4 content was 4%,conductivity was the highest.When nano-Fe3O4 content was 12%,reduction rate of I3-on the Pt electrode was the fastest.
