A new kind of agar‐polyacrylamide/graphene oxide (agar‐PAM/GO) nanocomposite double network (DN) hydrogels is successfully synthesized using one‐pot method. The agar‐PAM/GO DN hydrogel consists of first agar network cross‐linked via hydrogen bond and second PAM network with GO severing as physically cross‐linking agent. The factors that influence the mechanical properties of agar‐PAM/GO DN gel is investigated. The DN hydrogel exhibits excellent mechanical properties with fracture strain of 4 600% and fracture strength of 332 kPa. In addition, the DN hydrogel shows a good fatigue resistance and self‐healing ability.
