在国家自然科学基金等资助下,复旦大学邵正中教授和他的同事长期致力于天然蚕丝和蜘蛛丝聚集态结构研究,他们对丝素蛋白成纤机理、自组装规律和过程进行了深入研究,提出了在丝蛋白成纤过程中存在成核控制和构象转变的速度依赖性,发现在多方面蚕丝和蜘蛛丝成丝具有相似性。 2002年8月15日出版的《Nature》发表了邵正中教授和英国牛津大学Vollrath教授题为“Surprisingstrength of silkworm silk”的论文。 早在古代人们就已开始应用蚕丝。至20世纪高分子科学建立以后,人们才知道蚕丝是非生理活性的结构蛋白质类高分子,其性能与聚集态结构有密切关系。随着高分子科学的发展,人们发现力学性能最好的
Supported by the National Natural Science Foundation of China and other countries, Professor Shao Zhengzhong and his colleagues at Fudan University have long devoted themselves to studying the aggregate structure of natural silk and spider silk. They conducted an in-depth study on the fibrillation mechanism, self-assembly rules and processes of silk fibroin, The speed dependence of nucleation control and conformational transition in the process of fibroin fiber formation was proposed. It was found that silk fibroin and spider silk fibroin have similarities in many aspects. Nature, published August 15, 2002, published a paper entitled “Surprising strength of silkworm silk” by Professor Shao Chung-chung and Professor Vollrath at Oxford University in the United Kingdom. As early as ancient people have begun to apply silk. Until the 20th century after the establishment of polymer science, people only know that silk is a non-physiologically active structural protein macromolecules, its performance and aggregation state structure are closely related. With the development of polymer science, people find the best mechanical properties
