In the present work, a new strategy is proposed to simultaneously enhance the toughness and electrochemical performance of the hydrogel with conductive microgel to form microgel-reinforced double network hydrogel. In this hydrogel, the conductive microgel is cross-linked to form the first network, which can dissipate energy to improve mechanical performance and stabilize the conductive network to improve the electrochemical performance. These hydrogels show excellent mechanical properties and good conductivity. When these hydrogels are assembled to all-gel-state intrinsically flexible and stretchable supercapacitor, they deliver outstanding capacitance. The strategy put forward here can extend the application scope of the hydrogel with multifunction.
在本工作中，提出了一种新策略，即通过导电微凝胶来同时增强水凝胶的韧性和电化学性能，形成微凝胶增强的双重网络水凝胶。在这种水凝胶中，交联的导电微凝胶形成了第一个网络，它可以耗散能量来提高机械性能并稳定导电网络以提高电化学性能。这些水凝胶表现出优异的机械性能和良好的导电性。当这些水凝胶组装成全凝胶态的固有柔软和可拉伸超级电容器时，它们表现出优异的电容性能。这里提出的策略可以扩展具有多功能的水凝胶的应用范围。
