Abstract Graphene has an extremely high in-plane strength yet considerable out-of-plane softness. High crystalline order of graphene assemblies is desired to utilize their properties, however, challenged by the easy formation chaotic wrinkles for intrinsic Here, we find intercalation modulated plasticization phenomenon, present a continuous stretching method regulate spontaneous sheets into orders, and fabricate papers with Hermans’ 0.93. The paper exhibits superior mechanical (tensile 1.1 GPa, stiffness 62.8 GPa) conductive properties (electrical conductivity × 10 5 S m −1 , thermal 109.11 W K ). We extend ultrastrong realistic laminated composites achieve combining attractive electromagnetic shielding performance. plasticity revealed as vital state assemblies, contributing industrial processing metals plastics.
