  • Patent number: 12280518
    Abstract: Wood template-supported phase change material (PCM) composite having thermal energy storage applications. A wood template-supported PCM may include a wood template that has had at least a portion of its xylan and/or lignin removed and saturated with a PCM. The PCM may be stabilized with a cross linkable network for improved infiltration into the wood template. The wood template-supported PCM composite may be formed by extracting xylan and/or lignin from the wood to create a wood template, densifying at least a portion of the wood template, and inserting a PCM into the wood template.
