以纤维素/AmimCl溶液制备纤维素气凝胶(Cellulose aerogels prepared from cellulose/AmimCl solutions)
利用离子液体AmimCl 溶解结合超临界CO2 干燥的方法制备了纤维素气凝胶材料.研究了不同初始浓度的纤维素溶液及其在不同凝固浴中制备的纤维素凝胶的流变行为, 进一步考察了纤维素溶液浓度和凝固浴种类对纤维素气凝胶材料结构的影响. 结果表明, 随着初始纤维素溶液浓度的增大, 气凝胶的孔结构逐渐致密, 比表面积随之减小; 凝固浴的组成对纤维素气凝胶的结构也有较大影响. 采用适当的制备条件, 可以制备出高比表面积的纤维素气凝胶材料...

24. Bulk viscosity and its unstable behavior upon storage in polyimide precursor solutions. Tong YJ, Liu TX, Veeramani S, Chung TS. IND. & ENG. CHEM. RES. 41 (17): 4266-4272, 2002.
The bulk viscosity behavior of poly(amic acid) and its amine salt solutions, PAA(ODPA/o-tolidine) and PAS(ODPA/o-tolidine), has been investigated. Both PAA(ODPA/o-tolidine) and PAS(ODPA/o-tolidine) solutions show strong concentration and molecular weight dependence on bulk viscosity, and display critical values on the concentration dependence of bulk viscosity because of increasing the molecular c...
