课题组汪钟凯博士(与唐传兵教授合作)在ACS Macro Lett. 发表课题组第148篇论文 (ACS Macro Lett. 2016, 5, 220-223) (题目:Bioinspired High Resilient Elastomers to Mimic Resilin)

该探索的最初始思想来自2006-2007年,Ed Kramer教授提出人类皮肤力学性能可否在聚合物体系中得以真实的实现?

我们课题组坚持不懈,不断尝试,历时长达7年之久,终于在2014年初实现了该思想。

(Bioinspired Design of Nanostructured Elastomers with Cross-Linked Soft Matrix Grafting on the Oriented Rigid Nanofibers To Mimic Mechanical Properties of Human Skin. ACS Nano, 2015, 9 (1), pp 271-278)
这是聚合物物理与聚合物化学相结合的结晶!


之后,我们进一步拓展到了仿生节肢弹性蛋白的合成,也顺利实现。

Natural resilin possesses outstanding mechanical properties, such as high strain, low stiffness, and high resilience, which are difficult to be reproduced in synthetic materials. We designed high resilient elastomers (HREs) with a network structure to mimic natural resilin on the basis of two natural abundant polymers, stiff cellulose and flexible polyisoprene. With plasticization via mineral oil and mechanical cyclic tensile deformation processing, HREs show ultrahigh resilience, high strain, and reasonable tensile strength that closely mimic natural resilin. Moreover, the mechanical properties of HREs can be finely tuned by adjusting the cellulose content, providing the opportunity to synthesize high resilient elastomers that mimic different elastic proteins, such as elastin.
