| 摘 要： | 采用旋转流变仪对以1-乙基-3-甲基咪唑醋酸盐（EMIM]Ac）为溶剂的聚丙烯腈/纤维素溶液的流变性能进行了研究.结果表明,溶液表观黏度随浓度的升高而增大,但随剪切速率的增加而降低,为典型的切力变稀流体;单组分PAN溶液A黏度最低,单组分纤维素溶液F黏度最大,不同共混比溶液的黏度及对温度的依赖性均介于两纯组分PAN和纤维素Cell之间.

| Abstract: | The ionic liquid of 1-ethyl-3-methylimidazolium chloride （ EMIM ] Ac ） was used to dissolve polyacrlonitrile/cellulose, and then its rheological properties was studied with rotational rheometer. The results showed that： EMIM ] Ac was the good solvent both for cellulose and polyacrlonitrile. Solutions presented typical shear thinner fluid, the apparent shear viscosity decreased with the increase in shear rate, and increased with the increase in solutions＇ concentration. Single component PAN solution A had the lowest viscosity, while, the pure cellulose solution F had the highest, and viscosity of different blend ratio and the dependency to temperature both between pure solution PAN and cellulose. |
