摘要/Abstract

摘要： 以LiCl/DMAc为溶剂溶解棉浆粕，得到均匀透明的纤维素LiCl/DMAc溶液后，采用湿法工艺制备了纤维素薄膜。用红外光谱和X射线衍射等分析方法对薄膜结构进行了表征。考察了凝固浴种类、制膜液纤维素浓度、凝固浴中LiCl/DMAc浓度及凝固浴温度对薄膜力学性能的影响，得到了纤维素LiCl/DMAc溶液法制备纤维素薄膜的最佳工艺条件：配制纤维素质量分数为6-7%的纤维素LiCl/DMAc溶液，选用含有质量分数为10-15%的LiCl/DMAc的水溶液作凝固浴，固化温度为20℃时，可得到具一定强度的均匀透明的纤维素薄膜。

Abstract: The cellulose film was prepared using cellulose LiCl/DMAc solution which formed by cotton pulp dissolved in LiCI/DMAc solvent through wetting-spinning process . The Structure of cellulose film was characterized by means of FT-IR and XRD. The effects of the kind of coagulation bath、the cellulose concentration of cellulose LiCl/DMAc solution、the LiCl/DMAc concentration and temperature of coagulation bath on mechanical properties of the films were investigated. The results showed that the uniformly and transparent cellulose film with cartain intensity could be prepared when the cellulose concentration is 6-7％、the water solution which LiCl/DMAc containing is 10~15% and the temperature is 20℃ as coagulation bath.
