Ultrathin double-network hydrogels, which have super-high toughness under micro-scale thickness (elastic elongation _b > 1000%, tensile strength _b > 2 MPa and tearing energy G 600 J m^-2), and solvent-triggered fast and high isometric stress generation, were synthesized by coupling the salt-controlled swelling process and polymer chain pre-reinforced technique.
