摘要(Abstract)：

以碳纳米管(MCNT)和碳黑(CB)为添加剂,采用溶液共混的方法,讨论了添加剂浓度、放置时间、温度、剪切速率对聚丙烯腈溶液的表观黏度及黏流活化能(ΔΕη)的影响。结果表明:随着MCNT含量的增加,聚丙烯腈溶液的黏度先增大后减小,添加1.0%MCNT时,聚丙烯腈溶液的黏度最大,活化能也同时达到最大;随着碳黑含量的增加,黏度与活化能都随之增加,但增加幅度不大。两种PAN溶液都属于明显的切力变稀的非牛顿流体,随着剪切速率的增加,黏度下降;但在高切变速率(>800s-1)时,黏度几乎不变。
Micro-carbon/PAN solutions were prepared by blending carbon nanotubes(MCNT) and carbon black(CB).In this paper,the effect of micro-carbon concentration,time,temperature and shear rate on viscosity and activation energy of viscous flow(ΔΕη) were studied.The results indicated that the viscosity of PAN solution firstly increased along with the increase of MCNT concentration,and then decreased.When MCNT concentration was 1.0 %,the viscosity of solution was largest and the ΔΕη value also achieved a largest,the viscosity and ΔΕη increased along with the increase of carbon black concentration.Two varieties of PAN solutions belong to non-Newton fluid.The viscosity of PAN solution decreased along with shear rate increasing.But at higher shear rates(>800 s-1),the viscosity of the solutions were almost invariability.
