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.
