摘　　要：相变储能材料作为一种新兴热能储存材料,具有优异热管理能力,然而固-液类相变储能材料存在泄漏问题,限制其实际应用,目前主要利用微胶囊技术、多孔材料支撑技术解决其泄漏问题。木材作为一种天然多孔材料,具有天然分级各向异性孔道结构,利用孔道限域效应和表面张力,可作为理想支撑材料,有效解决相变储能材料的泄漏问题。本文系统总结定形相变储能木材的构筑策略,重点介绍功能型相变储能木材(高热导率、热致变色、荧光、电磁屏蔽、阻燃)最新研究进展,并分析目前相变储能木材研究中存在的问题及未来重点方向。相变储能木材的开发为拓展木材应用范围提供新径。As a novel thermal energy storage technology,phase change materials have excellent thermal management capabilities.However,the leakage issue of solid-liquid phase change energy storage materials limits their practical application.At present,microcapsule and porous supporting material technologies are used to address the leakage problem.Wood,as a natural porous material,exhibits hierarchical anisotropic channel structure that can serve as a supporting material to address the leakage problem of phase change materials,benefiting from its channel confinement effect and surface tension.In this review,the construction strategies for form-stable wood-based phase change composites are systematically summarized.In addition,the latest research progress of multifunctional wood-based phase change composites,such as high thermal conductivity,thermochromism,fluorescence,electromagnetic shielding,and flame retardant,is highlighted.Current challenges and future research directions in the field of wood-based phase change composites are discussed.The development of these composites offers a new way to expand the application range of wood.
