利用直流电，在添加CaCl2、MgCl2、FeCl3、钨酸钠的条件下，分别制备了KGM-Ca、KGM-Mg、KGM-Fe、KGM-T凝胶，对获得凝胶后电处理KGM溶胶电极两侧pH进行了测试,并对KGM-T凝胶进行了FTIR、Raman、SEM、XRD、DSC表征。结果表明，正极附近KGM溶胶为酸性，负极一侧KGM溶胶为碱性。SEM表明KGM在粉末状态下，外表呈现规则的微纤维状，KGM分子间有氢键；KGM溶胶冻干后呈现大小孔洞不均匀的支架结构，直流电处理的KGM溶胶冻干后的扫描电镜没有发生明显的变化，电处理未使KGM链的糖苷键发生断裂；KGM-Ca凝胶的表面形貌呈现大小孔洞不规则的絮状结构，KG...Konjac glucomannan (KGM) -Ca 、KGM-Mg 、KGM-Fe 、KGM-tungsten (KGM-T) gels were successfully produced under DC electric fields in the presence ofCaCl2、MgCl2、FeCl3 and sodium tungstate. pH experiments were conducted tomeasure pH value of DC treated KGM sol. And KGM-T gels were characterized byFTIR、Raman、SEM、XRD and DSC. pH experiments showed that KGM solcontaining Na2WO4.2H2O in the vicinity of the p...学位：博士后院系专业：材料学院_软物质与功能材料学号：201317006
