英文摘要	There is a challenge to prepare a hydrogel devoted to fabricate a form of multi-responsive skin-like sensors piggybacking on tactile controlled robots, which could grab the soft and fragile items at subzero temperatures. Herein, we demonstrate a supramolecular ionic liquid hydrogel wherein ureidopyrimidinone (UPy) containing hydrophilic polyurethane (PU) was employed as the network while the aqueous solution of imidazolium ionic liquid acted as a free phase. Combining the advantages of hydrophilic PEG segments, hydrophobic UPy moieties, and the imidazolium ionic liquid, this supramolecular hydrogel exhibited high water content (similar to 86%), swelling ratio (similar to 400%), elongation (similar to 750%), low resistivity (similar to 0.51 k Omega cm) and excellent transparency (similar to 98%). Moreover, the most striking characteristic was that the supramolecular hydrogel maintained its outstanding mechanical and thermal sensitivity at subzero temperatures, e.g., -20 degrees C. The supramolecular ionic liquid hydrogel was utilized to fabricate E-skin for the intelligent robot to realize pressure feedback and thermal recognition. This line of research not only demonstrates that anti-freezing stimuli-responsive hydrogels are a promising candidate for E-skins used in harsh conditions, but also contribute to the design and application of supramolecular polymer-based hydrogel sensors for future artificial intelligence applications.
