Rheological analyses and time-resolved SAXS experiments of the self-healing hydrogels. A Time-sweep experiments showing the storage moduli (G’) and loss moduli (G”) of the hydrogels against the gelling time at 1 Hz frequency and 1% dynamic strain. B Self-healing experiments showing the G’ and G” values of the equilibrium hydrogels at 1 Hz frequency and alternate continuous damage-healing cycles of 1 and 600% dynamic strains at 25 °C. C The steady shear-thinning properties of the hydrogels determined by measuring the viscosity versus shear rate. D Time-dependent coherent SAXS profiles acquired during the gelation process at 25 °C for investigation of microstructure changes of the hydrogel upon crosslinking. E SAXS profiles for the hydrogel at different temperatures. The SAXS data were obtained from COA2 hydrogel
