    Dissolving Bacterial Cellulose in Room Temperature Ionic Liquid

    • 摘要: 研究了细菌纤维素(BC)在绿色溶剂1-烯丙基-3-甲基氯代咪唑室温离子液体中的溶解行为,通过偏光显微镜观察了BC在此离子液体中的溶解过程,热失重(TGA)和红外光谱(FT-IR) 测试了再生前后BC的性能,探索了BC在离子液体中溶解、再生的可能性和可行性。结果表明:离子液体是BC的优良溶剂,对BC的溶解属于直接溶解,不发生其他的衍生化反应;再生后BC的热稳定性变好,且离子液体可回收利用。

       

      Abstract: Dissolution of bacterial cellulose (BC) in room temperature ionic liquid was studied as a green solvent, and the dissolving process was observed by the polarizing microscope. The structure of regenerated bacterial cellulose was characterized by TGA and FT-IR to probe into the possibility of dissolution and regeneration of BC in room temperature ionic liquid. Results show that 1-allyl-3-methylimidazolium chloride([AMIM]Cl) is good and direct solvent for bacterial cellulose without reaction of other derivative. The thermal stability of regenerated bacterial cellulose is good, and the ionic liquid can be recycled.
