Herein, we demonstrated the synergistic interfacial interactions of hydrogen bonding from hydroxypropyl cellu- lose and ionic bonding from copper ions upon the reduced graphene oxide based bioinspired nanocomposites, which show the integrated tensile strength, toughness and excellent fatigue-resistant property, as well as high electrical conductivity. These ex- traordinary properties allow this kind of bioinspired nanocomposites to potentially utilize in the fields of aerospace, flexible electronics devices, etc. This study also opens a door for fabricating excellent mechanical performance graphene-based bioin- spired nanocomposites via synergistic interfacial interactions in the future.展开更多
