Strengthening and Toughing Design of Graphene Oxide Based Artificial Nacre Composites Regulated by Dimensional Hierarchy of Ternary Structure

•Dimensional hierarchy GO-based ternary structure nacre-like composites were designed.•Dimensional hierarchy GO sheets induce a synergistic effect on strength and toughness.•Internal stress distribution can be improved by the dimensional hierarchy GO sheets.•More crack deflection can be triggered by the dimensional hierarchy GO sheets.•Nacre-like GO-based bulk composite can be easy prepared and achieve mass production.
