this article, the self‐healing hydrogels with reversible thermoresponses were designed through across‐linking‐induced thermoresponse (CIT) mechanism. The hydrogels were prepared from ketone group containing copolymer bearing tetraphenyl ethylene (TPE) and cross‐linked by naphthalene containing acylhydrazide cross‐linker. The mechanical property, light emission, self‐healing, and thermo‐response of the
具有热响应性的自愈水凝胶的开发对于人工智能材料非常重要。在本文中,通过交联诱导的热响应(CIT)机制设计了具有可逆热响应的自修复水凝胶。水凝胶由含酮基的四苯乙烯共聚物(TPE)制备,并通过含萘的酰肼交联剂交联。深入研究了水凝胶的机械性能,发光,自愈和热响应。在调节共聚物组成的情况下,水凝胶显示出LCST从高于体温到低于体温的热响应。同时,水凝胶基于酰基hydr键的可逆特性显示出自愈特性。水凝胶还显示出基于TPE单元的AIE特性的温度调节的发光行为。©2019 Wiley Periodicals,Inc.J.Polym。科学,A部分:Polym。化学2019,57,869-877
