| 摘 要： | 合成了溴代-1-丁基-3-甲基咪唑([Bmim]Br)离子液体,并配制成聚丙烯腈(PAN)/[Bmim]Br溶液。利用AR-1000型流变仪对PAN/[Bmim]Br溶液的静态和动态流变性能进行了研究,结果表明,8%(质量分数)的PAN/[Bmim]Br溶液接近牛顿流体,12%的溶液为假塑性流体;该体系的损耗模量和储存模量随溶液浓度的增大而增大,随温度的升高而减小。该研究为制定PAN的纺丝工艺提供了理论依据。

| Abstract: | The ionic liquid 1-butyl-3-methylimidazolium bromide was synthesized and used for further dissolving of PAN.The AR-1000 rheometer was employed to monitor the dynamic rheological and the static rheological properties of PAN/Br solution.The results indicate that the solution with a solute of 8% is approximate to Newtonian fluid and the that with 12% is a pseudoplastic liquid.Both loss and storage modulus of this system are enhanced with the increase of solution concentration and decreased with the increase of... |
