Bioinspired polyurethane structures with interfacial fluidity for improved impact attenuation

Superior impact toughness and enhanced strength of the brick-and-mortar design of nacre (mother-of-pearl), has made it a topic of intensive research in many fields of material science. Although numerous studies have demonstrated the mechanical robustness of the brick-and-mortar design, little is known about the two-dimensional impact attenuation characteristics of these structures. Herein, we develop brick-and-mortar based layered polyurethane …
