报告内容简介：

 In recent years, the development of various shape-memory and shape-changing materials in response to external triggers enables great potential applications. In this talk, I will first present two of my representative work on shapeshifting polymer materials. One is a cooling-triggered shapeshifting hydrogel based on double network hydrogels, which integrate a permanent network for elastic energy storage and a reversible hydrophobic network for ‘freezing’ temporary shapes under heating. Multiple temporary shapes were encoded independently at either different temperatures or different times during an isothermal process. The other one is a genetic mechanism for programming trigger-free shapeshifting based on dynamic bonds. Programmable shape-memory materials perform a sequence of encoded actuations under constant environment conditions without using an external trigger. Through strain-induced and time-dependent reorganization of the reversible hydrogen bonds, the dual network allows for encoding both the rate and pathway of shape transformations on time scales from seconds to hours. Then I will briefly talk a little about the bottlebrush polymer networks, where I will show how we can tune the mechanical properties by changing the architecture of polymer chains.
