Robust and functional graphene‐based nanocomposites are attractive in flexible electric devices. Herein, a strong and conductive bioinspired graphene‐based nanocomposite is demonstrated via multiple synergistic toughening effect from graphene oxide (GO), cellulose nanocrystals (CNC), and cadmium ion (Cd 2+ ). The multiple synergistic toughening effect can be realized from building blocks of 2D GO nanosheets and 1D CNC, interface interactions of hydrogen bonding from CNC and ionic bonding from Cd 2+ , resulting in integrated graphene‐based nanocomposites with high strength, and toughness as well as electrical conductivity. This ternary synthetic graphene‐based nanocomposite possessing outstanding physical properties provides a clear vision in the application of flexible electric devices. Furthermore, this bioinspired strategy could also serve as a guideline for the development of high‐performance graphene‐based nanocomposites in the future.
