摘要： Strong and tough structural materials are a challenging materials engineering problem that has drawn considerable attention among the materials community. Here we demonstrate that ternary supramolecular ensembles of cellulose nanocrystals-polyvinyl alcohol-glucose by evaporation-induced corporative assembly achieved simultaneous enhancement on the stiffness and toughness with the Young’s modulus of 13 GPa at the work-of-fracture of 1.1 MJ·m–3. Compositional alteration led to stiff and tough ternary ensembles with the Young’s modulus up to 14.7 GPa and the toughness up to 12.1 MJ·m–3, respectiv
