該探索的最初始思想來自2006-2007年,Ed Kramer教授提出人類皮膚力學性能可否在聚合物體系中得以真實的實現?
我們課題組堅持不懈,不斷嘗試,
歷時長達7年之久,
終于在2014年初實現了該思想。
感謝Ed! 感謝Zhongkai! 感謝治斌!
這是聚合物物理與聚合物化學相結合的結晶!

Human skin exhibits highly nonlinear elastic properties that are essential to its physiological functions. It is soft at low strain but stiff at high strain, thereby protecting internal organs and tissues from mechanical trauma. However, to date, the development of materials to mimic the unique mechanical properties of human skin is still a great challenge. Here we report a bioinspired design of nanostructured elastomers combining two abundant plant-based biopolymers, stiff cellulose and elastic polyisoprene (natural rubber), to mimic the mechanical properties of human skin. The nanostructured elastomers show highly nonlinear mechanical properties closely mimicking that of human skin. Importantly, the mechanical properties of these nanostructured elastomers can be tuned by adjusting cellulose
content, providing the opportunity to synthesize materials that mimic
the mechanical properties of different types of skins. Given the
simplicity, efficiency, and
tunability, this design may provide a promising strategy for creating
artificial skin for both general mechanical and biomedical applications.
