摘要
自修复水凝胶具有良好的可靠性、长期稳定性和可持续性,作为柔性传感器的基石,极大地推动了柔性电子领域的蓬勃发展。水凝胶的自修复性取决于网络中的动态可逆化学键,然而,开发具有优异自恢复性且满足柔性传感器实际应用需求的水凝胶仍具有挑战性。聚焦于自修复水凝胶网络设计策略和其在柔性传感器应用中的最新进展,重点介绍了基于动态可逆共价键和动态可逆非共价键的网络设计策略,以及其在电阻式、电容式和压电式柔性传感器中的应用,并对自修复水凝胶的未来发展进行了展望。
Self-healing hydrogels exhibit exceptional reliability,long-term stability,and sustainability.As a fundamental component of flexible sensors,they have significantly facilitated the vigorous advancement of the flexible electronics field.The self-healing capability of hydrogels depends on the dynamic reversible chemical bonds in the network.However,developing hydrogels with excellent self-healing that meet the practical requirements of flexible sensors was challenging.The paper reviewed the design strategies of self-healing hydrogels networks and the recent progress in flexible sensor applications,highlighted the two network design strategies based on dynamic reversible covalent bond and dynamic reversible non-covalent bond,and their applications in resistive,capacitive and piezoelectric flexible sensors.The future development of self-healing hydrogels was also prospected.
