报告题目：Development of hydrogels for applications in engineering fields
报告人：Insu Jeon 教授（韩国全南国立大学机械工程学院）
As a kind of soft materials, hydrogels are materials that consist of crosslinked polymer networks dispersed in water (Figure 1). While a number of promising properties, such as biocompatibility and environmental friendliness, responsiveness to external stimuli, adhesion, anti-biofouling behavior, and biodegradability have been integrated into the hydrogels, the relatively poor mechanical behavior of hydrogels remains a challenge, impeding their use in real-world applications that require mechanical integrity. In this talk, I am going to introduce strategies to design and fabricate various hydrogels, which have not only robust mechanical properties but elasticity, fast self-recovery, fast self-healing, good electrical properties, mechanical/electrical anisotropy and/or tuned shape deformation. These gels with multiple functionalities, are expected to open routes for the development of many useful functional devices for numerous engineering applications (Figure 2).
