利用偏光显微镜,扫描电子显微镜对木薯淀粉在2种离子液体中颗粒性质的变化进行测定和分析。结果表明:木薯淀粉在2种离子液体中溶解后形成澄清透明的均相体系,在溶解过程中,淀粉偏光十字逐渐消失,淀粉颗粒形貌发生变化,形成了不规则块状颗粒。

The properties of cassve starch in two kinds of ionic liquid were evaluated by polarized microscope and SEM.The results showed that cassava starch dissolved in ionic liquids to form a clear and transparent homogeneous system.During the dissolution,polarized cross of starch gradually disappeared,the shape of starch particles were totally changed and the formation of irregular particles occurred.
