Dual thermoresponsive chemical hydrogels, combining poly( N ‐isopropylacrylamide) side‐chains within a poly( N ‐acryloylglycinamide) network, are designed following a simple and versatile procedure. These hydrogels exhibit two phase transitions both at low (upper critical solution temperature) and high (lower critical solution temperature) temperatures, thereby modifying their swelling, rheological, and mechanical properties. These novel thermo‐schizophrenic hydrogels pave the way for the development of thermotoughening wet materials in a broad range of temperatures.
