小麦淀粉-离子液体溶液流变性质的研究

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。%The rheological properties of wheat starch-Cl solution were studied by using HAAKE rheometer.The results showed that wheat starch-Cl solution was a typical pseudoplastic fluid.The apparent viscosity of starch-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.
