摘要

The concept of self-healing that involves a built-in ability to heal in response to damage wherever and whenever it occurs in a material,analogous to the healing process in living organisms,has emerged a couple of decades ago.Driven primarily by the demands for life-like materials and soft smart materials,therefore,the development of self-healing polymeric hydrogels has continually attracted the attention of the scientific community.Here,this review is intended to give an in-depth overview of the state-of-the-art advances in the field of self-healing polymeric hydrogels.Specifically,recently emerging trends in self-healing polymeric hydrogels are summarized,and notably,recommendations to endow these hydrogels with fascinating multi-functionalities including luminescence,conductivity/magnetism and shape memory etc.are presented.To close,the current challenges and future opportunities in this field are also discussed.
