(A) Illustration of the synthesis of nanocomposite hydrogels. (B) Demonstration of the self-healing at room temperature. (C) Dependence of moduli on strain amplitude sweep (γ = 0.1–400%) at a fixed frequency of 1 rad/s. (D) Step-strain test at a fixed frequency of 1 rad/s (1% or 400% of strain). (E) Viscosity measurement at 1% of strain. (F) Printed cone and hollow cylinder 3D patterns. All these data were obtained using the hydrogel with the ration of PDMA-stat-PAPBA (wt %) : PGMA (wt %) : rGO@PDA (wt %) : PBA/diol (molar ratio) as 5.00 : 2.50 : 0.50 : 1/2.
