Biological materials exhibit fascinating mechanical properties for intricate interactions at multiple interfaces to combine superb toughness with wondrous strength and stiffness. Recently, strong interlayer entanglement has emerged replicate the powerful dissipation of natural proteins alleviate conflict between toughness. However, designing in a network needs be further explored. Here, we modulate by introducing interactions, including hydrogen ionic bonding, achieve ultrahigh performance graphene-based nacre fibers. Two essential modulating trends are directed. One is dynamic bonding improve up 1.58 GPa 52 MJ/m3, simultaneously. The other tailoring coordinating raise stiffness, reaching 2.3 253 GPa. Modulating various within robust provides an effective approach extend limits bioinspired optimize multiscale diverse composites.
