Owing to both solid- and liquid-like nature, gels are unique smart materials with several potential applications. However, most gels are inherently susceptible to harsh environments. Inspired by the “tun forming mechanism” of tardigrades, we proposed a simple two-step process to fabricate extremotolerant glycerogels with extremoprotected polymer-glycerol networks, which can survive from −50 to 80 °C for prolonged periods. The method is applicable to various types of polymers and crosslinkers and can be integrated with various functional materials to realize glycerogels with wide-ranging functionalities and properties. Therefore, this method dramatically enhances the selection of gels for bio, electrical/electronic, and soft robotics applications.
