However, low strength and toughness still hinder the practicality of existing ionogels. Inspired by the spider silk microstructure, we propose a strategy to simultaneously introduce woven crosslinks and multiple non-covalent interactions in a polymeric network to produce ionogels with excellent mechanical properties. Both woven crosslinks and non-covalent interactions dissipate energy to endow ultrahigh toughness to ionogel. Additionally, the rigid nature of woven crosslinks enhances the ionogel strength. Therefore, the ionogel exhibits high toughness (82.02 MJ m−3) and fracture energy (808.7 kJ m−2), healability, and recyclability. The toughness and fracture energy are superior to most previously reported ionogels. Moreover, this ionogel responds well to strains, indicating its potential use as a strain sensor. This strategy can lead to the production of other ionogels and hydrogels with intriguing mechanical properties.
