Cell engineering, soft robotics and wearable electronics often desire soft materials that are easy to deform, self-heal, and relax stress. Hydrogel, a type of hydrophilic networks, which can be made responsive to environmental stimuli, are often used in the aforementioned applications. However, conventional hydrogels often suffer from poor stretchability and repairability. Here, we report hydrogels consisting of boronic ester dynamic covalent bonds in a double network of poly(vinyl alcohol) together with chitosan, demonstrating extreme stretchability (up to 310 times of the original length), instant self-healing (within 5 sec), reusability as well as inherent adhesion. Their instant stress relaxation as a result of low activation energy of the boronic ester bond exchange (less than 20 KJ / mol) contributes to the extreme stretchability and self-healing behaviors. The hydrophilic environment readily incorporates various additives and provide opportunities in conductive soft materials, bio-signaling, and soft artificial joint.
