聚醚砜溶液流变性的研究

Study on the Rheological Behavior of PES/DMSO

摘要: 研究了聚醚砜（PES）/二甲基亚砜（DMSO）体系中PES的质量分数、原液温度对流变性的影响和原液中PES的质量分数对粘流活化能的影响,从而得出PES/DMSO体系属于切力变稀流体,非牛顿指数随着PES质量分数的增加而不断减小,随着溶液温度的升高而不断增大.

Abstract: The effect of the concentration of PES and the temperature of solution on the rheologicai behavior in the PES/DMSO system was studied. PES/DMSO solution is shear thinning. The non-Newtonican index of PES solution decreases with the increase of the concent
