Spinning Methods Used for Construction of One- and Two-Dimensional Fibrous Protein Materials.

Natural silk protein fibers have shown a great attraction to the researchers due to the extraordinary mechanical property, biocompatibility, and functional diversity. Unfortunately, the low yield and unevenness have hampered the scale use of the natural silk fibers. Herein, the appearance of the bioinspired artificial spinning strategy offers an effective way to fabricate silk fibers with controllable structures and functionality. This chapter describes an experimental method to prepare silk protein fibers on a large scale and summarizes the method to investigate the effects of the structure-property relationship of the recombinant protein fibers.
