The present disclosure relates to wood template-supported phase change material (PCM) composites having thermal energy storage applications. A wood template-supported PCM composite 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.

The invention relates to a method for producing OSB wood material panels, in particular OSB wood material panels having reduced emission of volatile organic compounds (VOCs), including the following steps: a) producing wood strands from suitable woods; b) torrefying at least some of the wood strands; c) glue-coating the torrefied wood strands and non-torrefied wood strands with at least one binder; d) scattering the glue-coated wood strands onto a conveyor belt; and e) pressing the glue-coated wood strands to form a wood material panel. The invention further relates to an OSB wood material panel that can be produced in accordance with said method and to the use of torrefied wood strands to reduce the emission of VOCs from OSB wood material panels.

A delignified wood material is formed by removing substantially all of the lignin from natural wood. The resulting delignified wood retains cellulose-based lumina of the natural wood, with nanofibers of the cellulose microfibrils being substantially aligned along a common direction. The unique microstructure and composition of the delignified wood can provide advantageous thermal insulation and mechanical properties, among other advantages described herein. The thermal and mechanical properties of the delignified wood material can be tailored by pressing or densifying the delignified wood, with increased densification yielding improved strength and thermal conductivity. The chemical composition of the delignified wood also offers unique optical properties that enable passive cooling under solar illumination.
