摘要
结晶化的丝蛋白具有高韧性和强度,是一种高性能材料,对其结构和功能的不断研究,有可能设计出在性能上接近或超过天然丝蛋白的新型材料。文章探讨了再生丝素蛋白结晶结构及其形成方法,包括变温法、有机溶剂诱导法、稀土金属配位结晶法等,同时介绍了一种存在于油-水界面处的新型液晶态丝蛋白,这一发现为通过液晶纺丝开发出新型高强再生丝素蛋白纤维奠定了基础。最后论述了丝素蛋白作为生物医用材料的广阔应用前景。
Crystallized silk fibroin with high tenacity and strength can serve as a high performance material. Intensive investigations on silk fibroin are expected to lead to new materials with better properties.In this paper different methods for crystallization of regenerated silk fibroin are concerned,including changing the temperature of solution, inducing via organic solvent,coordinating with rare earth metal etc. A new type of liquid crystalline state of silk fibroin existing at aqueous fibroin杘rganic solvent interfaces is also given here, which gives us an approach to exploit a new fibre derived from liquid crystal spinning of silk fibroin.The applications for a diverse set of clinical needs and other biomaterials are also discussed.
