Scalable aesthetic transparent wood for energy efficient buildings

This paper introduces a novel scalable aesthetic transparent wood (aesthetic wood) with combined aesthetic features (intact wood patterns), excellent optical properties (average transmittance of ~80%, haze of ~93%), good UV-blocking, and low thermal conductivity (0.24 W m⁻¹K⁻¹). The fabrication process involves spatially selective delignification and epoxy infiltration. Its rapid fabrication, mechanical robustness (high longitudinal tensile strength of 91.95 MPa and toughness of 2.73 MJ m⁻³), and scalability (320 mm × 170 mm × 0.6 mm) make it suitable for energy-efficient building applications.
