Isotropic Bouligand Wood with High Strength and Toughness
), outperforming many commonly used polymers and metals. The helicoidal architecture facilitates crack deflection and bridging mechanisms, substantially enhancing toughness, while hydrogen bonding strengthens the cellulose network and improves interfacial adhesion. Integrating structural design with cellulose's inherent molecular interactions enabled us to significantly reduce wood's anisotropy and realize a novel, high-performance wood-based structural material with well-balanced mechanical properties. This sustainable, mechanically isotropic material offers considerable promise for applications in construction, automotive, aerospace, and other engineering fields.
