The invention provides a hydrogel and a preparation method and application thereof. The hydrogel includes a first component, a second component and a third component, and the general structural formula of the first component is: The general structural formula of the second component is: The third component includes metal ions sited with the first component and/or the second component. The preparation method of hydrogel includes: mixing raw materials including initiator, cross-linking agent, acrylamide, polyvinyl alcohol, metal ion compound and solvent to obtain precursor liquid, and then performing polymerization reaction to obtain hydrogel. Application of hydrogels for fabrication of sensing devices, flexible energy storage devices and drug-loaded devices. The hydrogel provided by the present application has the characteristics of low hysteresis and excellent tear resistance and fatigue fracture ability. |
