The Effect of Ultrasonic Wave Pretreatment of Reed Leaf Cellulose Dissolved in Ionic Liquids

Abstract:

It took long time for reed leaf cellulose to dissolve in ionic liquid (1-butyl-3-methylimidazolium chloride), and part of the cellulose was degraded and the fiber strength reduced greatly. In order to decrease its dissolution time, the ultrasonic wave pretreatment was applied in this article. Results were showed through polarizing microscopy, SEM, FT-IR and XRD. By comparing the original fiber with the regenerated cellulose, it can be concluded that Ultrasonic wave pretreatment significantly increased the crystallinity of the fiber, weakened the fibrillation on fiber surface obviously, which proved the process was a physical change and did not affect the cellulose structure.
