Investigation of Surface Construction of Porous and Superhydrophobic Transparent Wood With High Haze

ABSTRACT Recent research on transparent wood has shifted from fundamental fabrication toward functional diversification, with superhydrophobic transparent wood demonstrating considerable promise. However, a critical challenge remains the insufficient interfacial bonding strength between the superhydrophobic coating and the transparent wood substrate. In this study, this limitation was addressed by constructing a porous surface structure on transparent wood via a facile processing route. Through the synergistic use of ultrasonic assistance and a mechanical anchoring effect, uniform and robust adhesion of hydrophobic materials to the substrate was achieved, enabling the fabrication of high‐performance superhydrophobic transparent wood. The resulting material, fabricated using 500‐grit sandpaper as a curing template, exhibits excellent optical properties (transmittance of 80.3% and haze of 89.7%), and pronounced superhydrophobicity, with a water contact angle of 153° and a sliding angle of 5.7°. In addition, it demonstrates outstanding wear resistance, self‐cleaning capability, dimensional stability, and low thermal conductivity. Moreover, the eco‐friendly preparation process combined with its comprehensive performance profile suggests strong potential for applications in architectural veneers and energy‐efficient furniture.
