“…Wood surface modification can improve the binding strength, optical properties, performance, stability, hydrophobicity, reactivity, and other properties of wood. Chemical modifications are conducted almost exclusively via the reactions of hydroxyl groups of cellulose, hemicelluloses, or lignin, such as esterification, etherification, oxidation, silylation, cross-linking, and grafting, as summarized in Figure C.…”

The building sector, including building operations and materials, was responsible for the emission of ∼11.9 gigatons of global energy-related CO2 in 2020, accounting for 37% of the total CO2 emissions, the largest share among different sectors. Lowering the carbon footprint of buildings requires the development of carbon-storage materials as well as novel designs that could enable multifunctional components to achieve widespread applications. Wood is one of the most abundant biomaterials on Earth and has been used for construction historically. Recent research breakthroughs on advanced engineered wood products epitomize this material’s tremendous yet largely untapped potential for addressing global sustainability challenges. In this review, we explore recent developments in chemically modified wood that will produce a new generation of engineered wood products for building applications. Traditionally, engineered wood products have primarily had a structural purpose, but this review broadens the classification to encompass more aspects of building performance. We begin by providing multiscale design principles of wood products from a computational point of view, followed by discussion of the chemical modifications and structural engineering methods used to modify wood in terms of its mechanical, thermal, optical, and energy-related performance. Additionally, we explore life cycle assessment and techno-economic analysis tools for guiding future research toward environmentally friendly and economically feasible directions for engineered wood products. Finally, this review highlights the current challenges and perspectives on future directions in this research field. By leveraging these new wood-based technologies and analysis tools for the fabrication of carbon-storage materials, it is possible to design sustainable and carbon-negative buildings, which could have a significant impact on mitigating climate change.

“…Many adhesives fail to bond wooden substrates due to their porous surfaces. 59,60 One important factor is the ability of adhesives to maintain contact with the wood surfaces without being absorbed into the substrate. Given the high adhesion on wood substrates, the rheology of TSE-50 adhesive resin at room temperature was studied (Fig.…”

“…The non-refluxed wood contains more carboxylic acid and hydroxyl groups, as suggested by the XPS spectra of C 1s and O 1s (shown in Table S1 in the Supplementary Materials). These functional groups could trap Na + ions or water molecules from the initial gel composition [19,20]. This behavior could affect the suitable gel ratio during the zeolite NaY formation and produce zeolite NaP, which requires a higher Na + content [21].…”

Zeolites in powder form have the potential to agglomerate, lowering access to active sites. Furthermore, a suspension of fine zeolite powder in liquid media is difficult to separate. Such drawbacks could be improved by dispersing zeolite crystals on support materials. This work demonstrates the dispersion of zeolite NaY crystals on bamboo wood by mixing the wood with zeolite gel before hydrothermal treatment. The syntheses were performed with acid-refluxed and non–refluxed wood. The phase of zeolites, particle distribution and morphology, zeolite content in the wood, and zeolite–wood interaction were investigated using X-ray diffraction, X-ray tomography, scanning electron microscopy, thermogravimetric analysis, nitrogen sorption analysis, and X-ray photoelectron spectroscopy. Higher zeolite content and better particle dispersion were obtained in the synthesis with the acid–refluxed wood. The composite of NaY on the acid-refluxed wood was demonstrated to be an effective adsorbent for Ni(II) ions in aqueous solutions, providing a higher adsorbed amount of Ni(II) per weight of NaY.
