Effect of In Situ Polymerization on the Thermal Stability and Enthalpy Properties of Wood‐Based Composites Based on Graphene Oxide–Modified Phase Change Microcapsule

ABSTRACT Encapsulation rate and thermal conductivity are crucial parameters for evaluating the properties of microencapsulated phase change materials (MEPCM). Graphene oxide (GO), as a two‐dimensional structure, has high thermal conductivity and is an amphiphilic material, and is expected to comprehensively solve this problem. In this study, a unique GO modified MEPCM was prepared with n‐octadecane as the core material and melamine urea–formaldehyde resin as the shell material. After delignification of balsa wood (DW), GO modified microcapsules were loaded into balsa wood by vacuum assisted impregnation. GO‐modified phase change microcapsule wood‐based composite was prepared. The prepared MEPCM was dispersed…
