本文研究了温度对由乙二醇和气相法白炭黑（质量分数为20%~ 26%）配制的剪切增稠液的影响。选择范围从20°C至60°C的三个典型温度来研究粘度的剪切速率依赖性。温度试验表明，高温使临界剪切速率增大，剪切增稠率降低。提出了一种表征剪切增稠流体三个特征区域的粘度函数，并对不同温度下的粘度进行了预测。
This paper is a study of the effect that temperature has on a shear thickening fluid made from ethylene glycol and fumed silica, with 20%–26% weight fractions. Three typical temperatures, ranging from 20°C to 60°C, were selected to study the shear rate dependence of viscosity. The temperature tests showed that a high temperature increased the critical shear rate and lowered the shear thickening ratio. A viscosity function was proposed to represent the three characteristic regions in typical shear thickening fluid and to predict viscosity at different temperatures.
