摘要
本研究以离子液体1-烯丙基-3-甲基咪唑氯盐([AMIM]Cl)为溶剂,以去离子水为凝固浴,对纤维素浆粕与废旧羊毛的溶解与再生过程进行了研究.采用偏光显微镜观察了纤维素和羊毛的溶解过程,研究了不同温度对它们溶解性能的影响以及纤维素及羊毛在不同温度下的溶解性能.通过傅里叶红外光谱(FTIR)、X射线衍射(XRD)及热重分析(TGA)等对其再生物进行了结构表征与性能测试.结果表明,[AMIM]Cl在一定条件下能够有效地同时溶解纤维素浆粕和废旧羊毛,且纤维素的加入有助于废旧羊毛再生为膜状材料,此外,所制备的再生纤维素/羊毛共混膜展现出更为优异的热稳定性.
Abstract
The dissolution and regeneration of cellulose pulp and waste wool were studied using ionic liquid 1-allyl-3-methylimidazolium chloride ([AMIM]Cl) as solvent and deionized water as coagulation bath.The dissolution processes of cellulose and wool were observed using a polarizing microscope,and the influence of different temperatures on their dissolution performance was explored.The structure and properties of the regenerated organisms were characterized by Fourier transform infrared spectroscopy (FTIR),X-ray diffraction (XRD) and thermogravimetric analysis (TGA).The research results indicated that[AMIM]Cl could effectively dissolve both cellulose pulp and waste wool under certain conditions,and the addition of cellulose helped to regenerate waste wool into membrane-like materials.In addition,the regenerated cellulose/wool blend membrane exhibited good thermal stability.
