中文摘要: 1-丁基-3-甲基咪唑氯盐([BMIM]Cl)、1-烯丙基-3-甲基咪唑氯盐([AMIM]Cl)、1-乙基-3-甲基咪唑亚磷酸盐([EMIM][P(CH3)OHO])等离子液体是纤维素和蛋白质的共同溶剂,以水为凝固剂,可以制备具有优良性能的新型全生物质再生纤维。利用变温红外、静态与动态激光光散射等方法研究纤维素/蛋白质在同一种溶剂中的相互作用机理,大分子链构象,聚集状态,分子间排斥体积及协同效应,共溶解原液的流动与凝固特性,纤维素/蛋白质/离子液体/水三元体系的凝固成形动力学,纺丝动力学及其结构演变机理。利用在线与离线同步辐射考察温度场、应力场、速度场等对纤维素/蛋白质复合纤维的多重结构与性能的影响规律。

英文摘要: The cellulose and protein can dissolved in the 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 1-allyl-3-methylimidazolium chloride ([AMIM]Cl) and 1-ethyl-3-methylimidazo liumphosphite ([EMIM][P(CH3)OHO]). The new regenerated all-biomass fibers with higher performance can be prepared by ionic liquids (ILs) as solvent and water as coagulant. Steady and dynamic state laser light scattering combine the variable temperature FTIR will be used to investigate the interaction mechanism of cellulose/protein in the same resolvent,conformation of macromolecualr chain,aggregation state,steric-exclusion and synergistic effect in inter-molecule,flow and coagulation of cosolvent,coagulation dynamics of cellulose/protein/ILs,dynamic spinning and evolution mechanism.The multiple structure and properties of regenerated cellulose/protein composite fibers influenced by temperature field、stress field and velocity field will be analyzed by on-line and off-line synchrotron radiation
