摘要: 采用哈克流变仪研究小麦淀粉-离子液体氯化1-烯丙基-3-甲基咪唑([AMIM]Cl)溶液的流变性质。结果表明:不同质量浓度的小麦淀粉-离子液体[AMIM]Cl溶液均为假塑性流体;离子液体溶液表现出黏度随剪切速率的升高而降低,溶液体系随着淀粉质量浓度增高而剪切稀化增强;溶液的触变性随温度的升高而减小。

Abstract: The rheological properties of wheat starch-[AMIM]Cl solution were studied by using HAAKE rheometer. The results showed that wheat starch-[AMIM]Cl solution was a typical pseudoplastic fluid. The apparent viscosity of starch-[AMIM]Cl solution exhibited an obvious decrease with increasing shear rate and shear thinning nature became more obvious with increasing starch concentration. The thixotropy dropped with increasing temperature .

Key words: wheat starch, ionic liquid, rheological property, apparent viscosity
