1. A method of forming a wood template-supported phase change composite, the method comprising:
extracting a xylan from a wood, resulting in a wood template;
densifying at least a portion of the wood template; and
inserting a phase change material into the wood template, wherein:
the phase change material comprises a material that can absorb or release heat when changing phase, and
the phase change material comprises polyethylene glycol and the stabilizing agent comprises poly(ethylene glycol) diacrylate.
