摘要/Abstract

摘要： 通过熔融共混挤出法制备了聚酰胺6(PA6)/离子液体复合材料切片，然后采用熔体流动速率仪和毛细管流变仪研究了离子液体含量对PA6/离子液体复合材料的流变行为影响。结果表明，PA6/离子液体复合材料的熔体流动速率随着离子液体含量的增加而增大；随着离子液体含量的增加和温度的升高，该体系的表观黏度逐渐降低，而非牛顿指数逐渐增加；随着离子液体含量的增加，PA6的黏流活化能逐渐降低；结构黏度指数随着温度的升高逐渐降低，而随着离子液体含量的增加，结构黏度指数呈先降低后增加的趋势。

Abstract: Polyamide 6(PA6)/ionic liquid composites were prepared by melt blending and extrusion. Effect of the content of the ionic liquid on rheological behaviors of the composites was investigated by melt flow indexer and capillary rheometer. The results indicated that the melt flow index of the composites was improved with increasing content of the ionic liquid. The apparent viscosity decreased with an increase of ionic liquid content and temperature, whereas the nonNewtonian index increased. Moreover, the viscous flow activation energy of the composites decreased with the increase of the ionic liquid contents. The structural viscosity index decreased with an increase of temperature at first and then trended to increase with increasing content of the ionic liquid.
