摘要：Introduction: Materials exhibiting a Poisson's ratio of zero have attracted considerable interest due to their unique properties and potential applications in various fields, including aerospace, athletic footwear, and sporting equipment. However, the high costs associated with their structural fabrication and the dependence on synthetic chemical materials for most zero Poisson's ratio materials complicate the preparation processes of current elastic materials, resulting in negative environmental impacts. Objectives: This study presents a sustainable treatment strategy that utilizes the inherent cellular structure of wood to achieve a zero Poisson's ratio, thereby enhancing its elasticity. Methods: By strategically selecting tree species with varying tissue compositions and employing simple chemical and heat treatments, we developed a commercially viable elastic wood material with a zero Poisson's ratio that meets diverse stress rebound requirements. Results: The unique internal s withstanding 5000 cycles of compression at a strain of 40 %-but also ensures excellent resilience and processability. At a deformati material retains its elasticity even at extremely low temperatures of 196 degrees C and demonstrates the abil-ity to endure elevated temper Conclusion: This study demo remarkable stability after cyclic compression, presenting a viable pathway for developing superelastic materials suitable for both hig (c) 2024 Published by Elsevier tructure of the wood not only provides high fatigue resistance-capable of on level of 60 %, the elastic modulus reaches 90.9 MPa.
