Abstract

Driven by the "Internet of Everything" (IoE) vision, the demand for smart materials is growing. Wood, one of the most abundant and renewable resources, has long been a staple in construction and furnishing applications. To further expand its application range, this study developed a high-strength, stable wood-based triboelectric material through a synergistic biphasic mechanism. The in situ growth of flame retardants and the formation of a dense char layer significantly enhanced the fire resistance of the wood-based triboelectric material, reducing the heat release rate (HRR) by 95.4% and total heat release (THR) by 94.2%. The dense laminate structure provided an excellent impact toughness (126 kJ m^-2). As a smart sensor, the wood-based triboelectric material demonstrated the ability to recognize human motion states and trajectories, exhibiting great potential for applications in smart homes. This study provides valuable insights for exploring the potential applications of wood as a smart material.

通过双相阻断技术实现强而稳定的木质三电材料。

在 "万物互联"（IoE）愿景的推动下，对智能材料的需求日益增长。木材是最丰富的可再生资源之一，长期以来一直是建筑和家具应用的主要材料。为了进一步扩大其应用范围，本研究通过双相协同机制开发了一种高强度、稳定的木基三电材料。阻燃剂的原位生长和致密炭化层的形成显著提高了木质三电材料的耐火性能，使热释放率（HRR）降低了 95.4%，总热释放率（THR）降低了 94.2%。致密的层压结构提供了出色的冲击韧性（126 kJ m-2）。作为一种智能传感器，木基三电材料具有识别人体运动状态和运动轨迹的能力，在智能家居领域具有巨大的应用潜力。这项研究为探索木材作为智能材料的潜在应用提供了宝贵的见解。
