Abstract:

The keratin nanofiber membrane prepared by electrospinning technology has great brittleness and poor mechanical properties by using pure keratin as raw material. Adding chemical additives can significantly improve the spinnability of keratin solution and improve the comprehensive properties of keratin nanofiber membrane. In this paper, three kinds of chemical assistants were introduced to optimize and improve the properties of keratin nanofiber membrane in the process of electrospinning, including spinning aids to improve the spinnability of spinning solution, cross-linking agents to enhance the comprehensive properties of nanofiber membrane and antibacterial agents to increase the special functions of nanofiber membrane. The mechanism of the above three kinds of chemical assistants in electrospinning keratin nanofiber membrane materials was discussed. The structure and properties changes the nanofiber membrane before and after the addition of chemical assistants were compared. The potential application and broad application prospect of chemical assistants in electrospinning keratin nanofiber materials were prospected. In the end, the research field in optimizing the comprehensive properties of electrospinning keratin nanofiber materials by adding chemical assistants in future were presented.

Key words: electrospinning, keratin, nanomaterials, chemical assistant, optimization

摘要:

以纯角蛋白为原料,采用静电纺丝技术制备的角蛋白纳米纤维膜脆性大、力学性能差,添加化学助剂能够明显改善角蛋白溶液的可纺性,提高角蛋白纳米纤维膜的综合性能。本文主要介绍了在静电纺丝过程中优化和改善角蛋白纳米纤维膜性能的三类化学助剂,包括改善纺丝液可纺性的助纺剂、增强纳米纤维膜综合性能的交联剂以及增加纳米纤维膜特殊功能的抗菌剂。阐述了以上三类化学助剂在静电纺角蛋白纳米纤维膜材料中的相关作用机理,对比了添加化学助剂前后角蛋白纳米纤维膜的结构和性能的变化情况,展望了化学助剂在静电纺角蛋白纳米纤维材料中潜在的应用价值和广阔的应用前景,提出了今后化学助剂在优化静电纺角蛋白纳米纤维综合性能方面的研究方向。
