摘　　要：硼酸酯键是一种特殊的动态共价键,室温下可在短时间内发生键合作用,反应速度快于大多数动态共价键,具有显著自愈合能力。采用合适的物理或化学交联策略,设计基于硼酸酯键交联的水凝胶,可赋予材料优异的理化性能。本文总结了近年来以纤维素等多糖或聚乙烯醇等多羟基聚合物为原料,基于硼酸酯键构筑的具有良好生物相容性的水凝胶,并介绍其所具备的突出性能,综述了其在生物医学领域和柔性电子器件方面的研究进展,为实现水凝胶多功能应用提供思路。Borate ester bond is a special type of dynamic covalent bond that can undergo bonding within seconds at room temperature,with faster reaction rate than most dynamic covalent bonds,and has significant self-healing ability.Using appropriate physical or chemical crosslinking strategy to design hydrogels based on borate ester bonds can give materials excellent physicochemical properties.In this paper,the hydrogels with excellent biocompatibility prepared by polysaccharide like cellulose and polyhydroxy polymers like polyvinyl alcohol based on borate ester bonds in recent years were summarized,and the outstanding properties were introduced.The research progress in the biomedical field and flexible electronic devices were reviewed,which provided an idea for achieving multi-functional applications of hydrogels.
