摘要

海藻酸钠纤维因其无毒、高保湿性、高透氧性、生物相容性和可生物降解性而受到广泛的研究。然而，由于其机械性能较差，其应用受到限制。本研究将聚乙二醇二缩水甘油酯醚改性海藻酸钠纤维通过喷丝器将混合反应后的溶液纺丝至含氯化钙的混凝浴中。考察了纺丝液的性能，以及不同聚乙二醇二缩水甘油酯含量改性海藻酸钠纤维的结构和物理性能。改性海藻酸钠纤维的聚乙二醇二缩水甘油醚含量为15wt %时，其断裂强度和断裂伸长率分别比纯海藻酸钠纤维提高78%和114%，达到最佳。改性海藻酸钠纤维的热稳定性也得到了改善。

Facile Fabrication of Chemically Modified Sodium Alginate Fibers With Enhanced Mechanical Performance

Sodium alginate fibers have been extensively studied due to being non-toxic and have high moisture retention, high oxygen permeability, biocompatibility, and biodegradability. However, their application has been limited due to their poor mechanical performance. In this study, poly(ethylene glycol) diglycidyl ether-modified sodium alginate fibers were prepared by spinning the solution after mixed reactions through a spinneret into a coagulation bath containing aqueous CaCl2. The properties of the spinning solution, the structure and physical properties of the modified sodium alginate fibers with various poly(ethylene glycol) diglycidyl ether contents were investigated. A poly(ethylene glycol) diglycidyl ether content of the modified sodium alginate fibers of 15 wt% gave optimal breaking strength and elongation at break, improving them by 78 % and 114 %, respectively, compared with pure sodium alginate fibers. The thermal stability of the modified sodium alginate fibers was also improved.
