Mechanical properties and structural evolution of supramolecule hydrogels. a Representative tensile stress–strain curves, b breaking elongation and tensile strength, as well as c Young’s modulus and toughness of PNASC, P(NASC-co-AAc), P(NASC-co-AAm), and PNAA hydrogels. d Typical tensile stress–strain curves, e breaking elongation and tensile strength, as well as f Young’s modulus and toughness of PNAA supramolecule hydrogels with different AAm and AAc content and mass ratios. g 2D SAXS scattering patterns and corresponding h 1D SAXS profiles of a PNAA0.5–1/3 hydrogel under different stretching strains. i Schematic illustration of the strengthening and toughing mechanism of PNAA hydrogels through microphase separation domains.
