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.

具有双重热响应机械性能的水凝胶

按照简单而通用的程序设计了双重热响应性化学水凝胶，在聚N-丙烯酰基甘氨酰胺网络中结合了聚N-异丙基丙烯酰胺侧链。这些水凝胶在低温（较高的临界溶液温度）和高温（较低的临界溶液温度）下均表现出两个相变，从而改变了它们的溶胀，流变性和机械性能。这些新型的热精神分裂症水凝胶为在宽温度范围内开发热增韧湿材料铺平了道路。
