摘　　要：以不同组成比的PVDF/PEG复合制成微多孔状材料,然后利用该材料与锂盐制备复合电解质薄膜,并对所得薄膜样品进行偏光显微镜(POM)、X射线衍射(XRD)及扫描电子显微镜(SEM)分析和表征.通过对比微多孔状材料表面的PVDF/PEG复合电解质膜与未加致孔剂的PVDF/PEG薄膜的导电性能,研究表面微观结构对离子导电行为的影响.结果表明,PVDF/PEG复合电解质薄膜对乙酸蒸气具有择优性响应性,在复合薄膜中引入微多孔结构,增大了比表面积,响应性能明显改善.In the experiment,PVDF/PEG composite made of different composition ratio was used to prepare micro porous material and lithium salt to prepare composite electrolyte thin film.These conductivity films were characterized by polarizing optical microscopy,XRD,SEM.By comparing the conductivity of PVDF/PEG composite electrolyte membrane and PVDF/PEG film without porogen,the influence of surface microstructure on ionic conduction behavior is studied.The results show that PVDF/PEG composite electrolyte film has excellent response to acetic acid vapor,and the micro porous structure is introduced into the composite film,which increases the specific surface area and improves the response performance.
