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 (Cd²⁺). 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 Cd²⁺, 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.

通过镉离子和纤维素纳米晶体的多种增韧增韧石墨烯纳米复合材料

功能强大且功能强大的基于石墨烯的纳米复合材料在柔性电子设备中具有吸引力。本文通过氧化石墨烯（GO），纤维素纳米晶体（CNC）和镉离子（Cd ²⁺）的多重协同增韧作用证明了一种强大且导电的生物启发性石墨烯基纳米复合材料。可以从2D GO纳米片和1D CNC的构造块，CNC的氢键与Cd ^2+的离子键的界面相互作用中实现多重协同增韧效果。，从而获得具有高强度，韧性和导电性的集成石墨烯基纳米复合材料。这种具有出色物理性能的三元合成石墨烯基纳米复合材料为柔性电子设备的应用提供了清晰的视野。此外，这种受生物启发的策略还可作为将来开发高性能石墨烯基纳米复合材料的指南。
