摘要
水凝胶作为一种由大量水和与众不同的三维网状结构构成的智能软材料,已经广泛应用于许多领域,如药物输送、软骨修复、废物处理及电子设备等。然而,水凝胶不良的机械性能及自愈合性极大地限制了它们的潜在应用。目前已报道的韧性水凝胶通常不具有或只有很弱的自修复性,而自修复水凝胶通常机械性能非常弱。因此,研发具有高效自修复性能和优异机械性能的水凝胶材料,无论是从学术角度还是工业角度都是非常重要的。本文总结了近些年来强韧型自愈合水凝胶的最新研究进展,从其制备方法、性能等方面进行了简要介绍,并对未来的发展前景进行了展望。
Hydrogels,a kind of smart soft material that consists of water and distinctive 3D cross-linked network structures,have been widely used in many fields,such as drug delivery,cartilage repair,waste treatment and electronic equipment.However,the applications of hydrogels are often limited by their poor mechanical properties and self-repairing capability.Currently,the reported tough hydrogels are usually not or only weakly self-repairing,and self-healing hydrogels are usually very weak in mechanical properties.Developing hydrogel materials with both high mechanical strength and self-healing properties is significant from both academic and industrial points of view.The present paper summarizes the development of tough self-healing hydrogels covering from preparation methods,network structures,to properties.It provides an outlook of the perspective of tough self-healing hydrogels.
