以离子液体1-丁基-3-甲基咪唑氯盐([BMIM]Cl)为溶剂,溶解棉浆粕得到均匀透明的纤维素溶液,采用湿法工艺制备纤维素薄膜,并研究了凝固浴浓度对纤维素薄膜微孔结构和力学性能的影响。结果表明,选用质量分数为20%的离子液体水溶液作凝固浴可得到具有一定强度的均匀透明的纤维素薄膜。
The ionic liquid 1-butyl-3-methylimidazolium chloride ([BMIM] Cl) was used as a solvent to dissolve the cotton pulp to obtain a uniform and transparent cellulose solution. The cellulose film was prepared by the wet process and the coagulation bath Effect of Concentration on Micropore Structure and Mechanical Properties of Cellulose Films. The results show that the selection of a mass fraction of 20% ionic liquid aqueous solution as the coagulation bath can be obtained with a certain intensity uniform transparent cellulose film.
