Severe pressure from energy consumption and serious pollution from non-renewable resources have urged human beings to develop green and energy-efficient materials. Transparent wood, consisting of original wood channel structure filled with resins, has favorable environmental friendliness and high transparency and haze, which holds huge potential in various important fields. Herein, a brief review of the current research activities centered on the development of transparent wood is provided. This review begins with an introduction to the background of transparent wood. Next, the cellular wall structure of wood and the synthetic strategy of transparent wood (including decolorization and impregnation) are summarized. Furthermore, the functionalization of transparent wood through doping nanomaterials or modifying resins is highlighted, and the relationship between the physicochemical properties and the potential uses (like optoelectronics, building materials, and furniture decoration) of transparent wood is clarified. Finally, a brief overview of the prospects and challenges for transparent wood is provided.

能源消耗的巨大压力和不可再生资源的严重污染促使人类发展绿色节能材料。透明木材由树脂填充的原始木材通道结构组成，具有良好的环境友好性和高透明度和雾度，在各个重要领域具有巨大的潜力。在此，简要回顾了当前以开发透明木材为中心的研究活动。这篇评论首先介绍了透明木材的背景。接下来，总结了木材的蜂窝壁结构和透明木材的合成策略（包括脱色和浸渍）。此外，突出了通过掺杂纳米材料或改性树脂对透明木材进行功能化，阐明了透明木材的理化性质与潜在用途（如光电、建筑材料和家具装饰）之间的关系。最后，简要概述了透明木材的前景和挑战。
