Abstract
AbstractThe combination of optical transparency and mechanical strength is a highly desirable attribute of wood‐based glazing materials. However, such properties are typically obtained by impregnation of the highly anisotropic wood with index‐matching fossil‐based polymers. In addition, the presence of hydrophilic cellulose leads to a limited water resistance. Herein, this work reports on an adhesive‐free lamination that uses oxidation and densification to produce transparent all‐biobased glazes. The latter are produced from multilayered structures, free of adhesives or filling polymers, simultaneously displaying high optical clarity and mechanical strength, in both dry and wet conditions. Specifically, high values of optical transmittance (≈85.4%), clarity (≈20% with low haze) at a thickness of ≈0.3 mm, and highly isotropic mechanical strength and water resistance (wet strength of ≈128.25 MPa) are obtained for insulative glazes exhibiting low thermal conductivity (0.27 W m−1 K−1, almost four times lower than glass). The proposed strategy results in materials that are systematically tested, with the leading effects of self‐adhesion induced by oxidation rationalized by ab initio molecular dynamics simulation. Overall, this work demonstrates wood‐derived materials as promising solutions for energy‐efficient and sustainable glazing applications.
