China, the birthplace of silk, boasts a sericulture heritage dating back to the Yangshao Culture period (5000-3000 BCE), as evidenced by archaeological discoveries. Techniques for mulberry cultivation, silkworm rearing, silk reeling, and fabric weaving advanced significantly during the Spring and Autumn and Warring States periods, ultimately propelling Chinese silk to global prominence via the ancient Silk Road.

In the modern era, China’s "Belt and Road Initiative" — revitalizing the Silk Road’s legacy through the "New Silk Road Economic Belt" and the "21st Century Maritime Silk Road" — has infused the sericulture and silk industry with fresh challenges and transformative opportunities.

Now, this ancient material is experiencing a scientific renaissance. Through cutting-edge research in polymer materials, silk is unveiling a new realm of possibilities, bridging millennia of tradition with tomorrow’s innovations.

Professor Tongyin Yu, founding director of the Department of Polymer Science at Fudan University, pioneered China’s polymer science discipline. In his late 60s, Professor Yu spearheaded groundbreaking research in biopolymers, marking a visionary expansion into this emerging field. As later reflected, "The journey of Fudan’s polymer science can be said to encapsulate half the history of China’s polymer science development."

2On August 15, 2002, Professor Shao’s groundbreaking research on silk was published as a brief communication in Nature, marking a new chapter for China’s polymer science on the global academic stage.

From 2002 to the present, silk fibroin—extracted through advanced sericulture—has emerged as an innovative biomaterial within the commercial landscape. Through progressive regulatory standardization and industrial refinement, it has now entered a phase of broadened application scenarios, spanning biomedical engineering, eco-friendly textiles, and advanced cosmetics.
