摘要
分别对传统水凝胶的缺点及引入动态共价键的水凝胶的优点进行了阐述,同时简单阐述了自愈性水凝胶的两种不同自愈机制及其优缺点。首先总结了能够制成自愈性水凝胶的四种典型动态共价键类型及其特点,包括席夫碱键、二硫键、硼酸酯键和Diels-Alder(D-A)反应。其次介绍了将动态共价键引入水凝胶中不仅可以提高水凝胶的自愈性能,还可以提高其响应能力、敏感性、力学性能和导电性。最后对基于动态共价键的水凝胶用于柔性电容式压力传感器、压电式应变传感器和电阻式应变传感器在运动监测领域的研究进展进行了介绍,并指出未来构建低成本、高性能的柔性传感器仍然是该领域的发展方向。
Disadvantages of conventional hydrogels and advantages of hydrogels with dynamic covalent bonds are discussed respectively.Two different self-healing mechanisms of self-healing hydrogels and their advantages and disadvantages are also briefly described.Firstly,four typical types of dynamic covalent bonds capable of making self-healing hydrogels and their characteristics are summarized,including Schiff base bond,disulfide bond,borate bond and Diels-Alder(D-A)reaction.Secondly,it is introduced that the introduction of dynamic covalent bond into hydrogel can improve its self-healing performance,and its response capability,sensitivity,mechanical properties and conductivity.Finally,the research progress of hydrogels based on dynamic covalent bond for flexible capacitive pressure sensor,piezoelectric strain sensor and resistive strain sensor in the field of motion monitoring is introduced.It is pointed out that the construction of low-cost and high-performance flexible sensors is still the development direction of the field in the future.
