| 摘 要： | 以纤维素(Cell)和南极磷虾蛋白(AKP)为原料，以乙二醇二缩水甘油醚（EGDE）为潜在交联剂，NaOH和尿素水溶液作溶剂，在低温下溶解Cell和AKP后，加入EGDE制备Cell-AKP-EGDE复合纺丝原液，将纺丝原液挤入H2SO4-Na2SO4-H2O构成的凝固浴中，经热拉伸定型获得EGDE原位交联的Cell-AKP复合纤维。利用FTIR研究了交联剂EGDE的含量对Cell-AKP复合体系分子间相互作用的影响，采用SEM、XRD、TG等考察了交联剂EGDE的含量与Cell-AKP复合体系的表面形态、结晶性、热稳定性和力学性能的相关性。结果表明:交联剂EGDE含量的不同对Cell-AKP复合纤维的表观黏度、力学性能、结晶性及表面形态等均有影响，且交联剂EGDE含量为3wt%时，Cell-AKP复合纤维的综合性能较好。

| Abstract: | Taking cellulose (Cell) and antarctic krill protein (AKP) as the raw materials, ethylene glycol diglycidyl ether (EGDE) as the latent crosslinker, NaOH and urea aqueous solution as the solvents, Cell-AKP-EGDE composite spinning solution was prepared after dissolving Cell and AKP at low temperature. Then the spinning solution was squeezed into a coagulation bath composed of H2SO4-Na2SO4-H2O, and the Cell-AKP composite fibers crosslinked in situ by EGDE were obtained by hot stretching. The effect of the content of EGDE on the intermolecular interaction of Cell-AKP composite system was studied by FTIR. The correlation between cross-linking agent content and the surface morphology, crystallinity, thermal stability and mechanical properties of Cell-AKP composites was investigated by SEM, XRD and TG. The results show that the apparent viscosity, mechanical properties, crystallinity and surface morphology of the Cell-AKP composite fibers are affected by the content of EGDE crosslinking agent, and the comprehensive properties of the Cell-AKP composite fibers are the best when the content of EGDE crosslinking agent is 3wt%. |
