摘　　要：基于动态硼酸酯键构筑的聚合物有一定的自修复能力和对刺激的多重响应性,能够通过诱导材料内部物理/化学结构的拓扑重组并以此来响应生物信号的变化。本文综述了基于水解/再酯化、二醇硼酸酯之间的酯交换和硼酸酯之间的酯交换3种不同的硼酸酯酯交换机制构筑的多种天然/非天然高分子材料;通过传统共价键和硼酸酯动态共价键协同作用设计更加稳定的四面体硼酸盐结构来解决硼酸酯基聚合物稳定性较差的策略;硼酸酯基聚合物在生物医药、传感器和可回收材料等多领域的应用潜力。重点介绍了硼酸酯键与其它动态键协同作用制备理想的聚合物材料,如水凝胶、有机凝胶、液晶材料和可回收纳米材料等。The polymers based on dynamic borate bonds had certain self-healing ability and multiple responses to stimuli,and they could respond to biological signal changes by inducing topological recombination of physical/chemical structures in the materials.A variety of natural/non-natural polymer materials based on three different transesterification mechanisms of borate esters were reviewed in this paper,namely hydrolysis/re-esterification,transesterification between diol and borate and transesterification between borate and borate.It was a strategy to design a more stable tetrahedral borate structure through the synergistic effect of traditional covalent bond and borate dynamic covalent bond to solve the borate ester polymer short plate.Application potential of borate-based polymers in many fields was summarized,such as biomedicine,sensors and recyclable materials.The synergistic of borate ester bond and other dynamic bonds to prepare ideal polymer materials was mainly emphasized,such as hydrogels,organic gels,liquid crystal materials,recyclable nanomaterials,etc.
