AbstractBC was activated by ethylenediamine, and then the resulting product (ABC) was dissolved in lithium chloride/N, N-dimethylacetamide aqueous solutions. The regenerated BC (RBC) was prepared by the solution cast method. Then RBC was dissolved in NaOH/urea aq
Other Abstract纤维素经过活化、再生后可以溶解在氢氧化钠/尿素体系中。本文研究了乙二胺活化对细菌纤维素结晶度的影响规律,得到最佳活化条件;然后将活化后的细菌纤维素在LiCl/DMAc体系中溶解再生,得到再生细菌纤维素。最后,使用氢氧化钠/尿素溶液作为再生细菌纤维素的复合溶剂,得到的细菌纤维素的水溶液。通过红外光谱、X射线衍射仪、热重分析仪等分析了细菌纤维素不同处理阶段得到产物的性能。溶解与再生并没有发生化学变化,纤维素的结构基本保持不变,但结晶度有所降低,热稳定性有所提高。
