摘要/Abstract

摘要：

醋酸纤维素在N,N-二甲基甲酰胺(DMAc)中难以进行静电纺丝，将其与芳纶溶液混合后成功制备了芳纶/醋酸纤维素纳米纤维。芳纶/醋酸纤维素混合溶液有利于静电纺丝，当芳纶/醋酸纤维质量比大于1:2后即可获得均匀的纳米纤维。随混合溶液中芳纶/醋酸纤维素的质量比和溶液质量分数的提高，纳米纤维中的珠状缺陷逐渐减少。芳纶/醋酸纤维素纳米纤维的热稳定性较纳米芳纶明显提高。纳米芳纶在150℃附近存在一个热失重过程，而芳纶/醋酸纤维素纳米纤维在这一阶段的热失重温度升至250℃左右。

Abstract:

The cellulose acetate/ DMAc solution is unable to be electrospun into ultra fine fiber. However, the cellulose acetate/meta-aramid solution with a mass ratio 1:2 can be successfully electrospun into uniform nanofibers. The beads on the nanofibers decreased gradually as the mass ratio of cellulose acetate/meta-aramid in the solution and the mass concentration of the solution increased. The thermal property of cellulose acetate/meta-aramid nanofibers improved significantly as compared with aramid nanofibers, and the thermal loss process of aramid nanofibers occurred at around 150℃, whereas it occurred at 250℃ for cellulose acetate/meta-aramid nanofibers.
