摘　　要：水凝胶是三维网状亲水聚合物,其中的自愈合水凝胶是一种特殊机制的材料,因含有可逆共价键或以非共价交联,具有自修复的能力。主要综述了目前用于广泛研究的以天然多糖为原料制备自愈合水凝胶及其交联机理,对于进一步研究自愈合水凝胶在拓展创新、实践应用等各方面具有挑战性的突破和指导性意义。Hydrogel is a three-dimensional network of hydrophilic polymers.The self-healing hydrogel is a material with a special mechanism,which has the ability of self-healing due to the reversible covalent bond or non-valent cross-linking.This paper mainly reviews the preparation of self-healing hydrogels and their crosslinking mechanism using natural polysaccharides as raw materials,which are currently used for extensive research.It is of guiding significance for further research on the challenging breakthroughs of self-healing hydrogels in expanding innovation and practical applications.
