The invention discloses double-network ionic gel with stimulation responsiveness and self repairability. Ionic liquid serves as a substrate, P(VDF-co-HFP) is used as a physical cross-linking network,dynamic covalent bond cross-linked PMA (polymethacrylate) copolymer serves as a chemical cross-linking network, and the two polymer cross-linking networks penetrate mutually to form a double network.Under synergistic effects of the double network, the ionic gel is excellent in mechanical performance, thermal stability and ionic conductivity. In addition, due to containing of reversible dynamic covalent bonds, self repairability under stimulation of light, thermal and the like can be realized. The ionic gel can be widely applied to lithium ion battery solid-state polyelectrolyte materials, gasseparation membranes, flexible electric devices, electrochemical sensors and the like.
