| 摘 要： | 采用蒸汽闪爆技术对天然纤维素进行改性处理,对处理前后的纤维素进行了溶解度测试、SEM及X-射线衍射分析,研究表明,蒸汽闪爆破坏了纤维素分子内氢键,使改性后的天然纤维素在一定温度下可直接完全溶解于特定浓度的NaOH水溶液中,且适当润胀剂的加入也有利于纤维素在NaOH水溶液中的溶解。 |
| 关 键 词： | 天然纤维素 蒸汽闪爆 SEM观察 X-射线衍射 |

| Abstract: | A new steam explosion pretreatment of natural cellulose was studied in this paper. The solubility towards aqueous alkali solution, SEM observation and X-ray diffraction patterns of original and regenerated cellulose indicated that steam explosion can break intra-molecular hydrogen bond of cellulose which makes natural cellulose dissolve completely in the aquenous NaOH solution with specific concentration at 4℃, and proper sweller is beneficial to the solubility of cellulose towards aqueous alkali solution. |
| Keywords: | natural cellulose steam explosion SEM observation X-ray diffraction |
