摘要：Wood is an important raw material for manufacturing phase change energy storage materials for indoor application. However, it is a hard nut to crack to balance the energy storage efficiency with the physical performances of the products. In this study, a heterogeneous encapsulation strategy of phase change material and enhancement component in wood cell for manufacturing phase change energy storage composites with high mechanical performance and dimensional stability was proposed. The construction mechanism, energy storage properties and physical mechanic performances of the prepared wood-based phase change energy storage composites were carefully analyzed. Results show that the coordination of energy storage function and physical performances in plantation wood could be realized by the two-step heterogeneous recombination of PEG 800 and epoxy polymer. Wood processed energy storage function after some PEG 800 filled in cell cavities. The dimensional stability of the wood was synchronously improved by the PEG 800 introduced into cell walls. The treated wood was reinforced after introducing water soluble epoxy monomer into the cell cavity below the melting point temperature of PEG 800 and its polymerization in-situ at low temperature. When the concentration of PEG 800 solution reached 40% at the first step, the energy storage material obtained in this study could process adequate comprehensive performances. This study will effectively promote the practical application of wood-based energy storage materials. ? 2024, The Authors. All rights reserved.
