摘要：
Silkworms and spiders are capable of generating fibers that are both highly durable and elastic in a short span of time, using a silk solution stored within their bodies at room temperature and normal atmospheric pressure. The dragline silk fiber, which is essentially a spider's lifeline, surpasses the strength of a steel wire of equivalent thickness. Regrettably, humans have yet to replicate this process to produce fibers with similar high strength and elasticity in an eco-friendly manner. Therefore, it is of utmost importance to thoroughly comprehend the extraordinary structure and fibrillation mechanism of silk, and leverage this understanding in the manufacturing of high-strength, high-elasticity fibers. This review will delve into the recent progress in comprehending the structure of silks derived from silkworms and spiders, emphasizing the distinctive attributes of solidstate NMR.
