“…[11b] Though the toughness of TW is crucial for practical applications, especially for building applications, little research has been expended on this topic. Recently, Jungstedt et al [66] investigated the transverse fracture toughness of TW. Their results indicated that the fracture toughness of TW might be highly related to the intercellular peeling energy, which may decrease during the delignification process (removal of the lignin-rich middle lamella between fibers).…”

“…Therefore, two possible strategies for improving the fracture toughness were proposed. [ 66 ] One is impregnating polymers into the delignified interfiber region. Another is selecting other methods for selectively degrading the chromophores rather than delignification.…”

Transparent wood (TW)‐based materials have increasingly become the focus of researchers worldwide owing to their superior physico‐chemical‐optical properties, sustainable nature, as well as the fact that they are highly accommodating frameworks that can act as building blocks to readily explore a vast range of potential functionalities, holding great potential to displace glass and plastics in their various respective applications. The integration of multiple functionalities into TW has been undertaken to fulfill the demands of prospective sophisticated applications through the utilization of functional fillers or coatings. Herein, the up‐to‐date foundational developments and reports concerning emergent TW composites and coatings from a perspective of fabrication‐functionality‐application are comprehensively summarized, with a particular focus on seven specific functionalities; i) solar control; ii) chromically‐responsive, iii) electrically‐conductive, iv) shape‐memory active; v) flame‐retardant; vi) electromagnetic interference shielding; and vii) aesthetics. The potential applications of TW with these functionalities are also discussed. Finally, the current challenge with TW is addressed, as well as the future developments required for eventual real‐world application.

“…The lower fracture toughness is related to the lower local strength for cell wall peeling and fiber cross-over bridging mechanisms, which are less fracture resistant than pull-out and fiber breakage mechanisms [17]. For this reason, crack growth in the weak RL and TL fracture planes is common during failure of native wood and TW composites [18]. The fracture toughness of wood is anisotropic also in a more general sense, and at least eight crack paths have been defined [12].…”

“…These CZM parameters facilitate analysis of crack growth micromechanisms; the CZM approach also gives more information for materials design purposes than point criteria (K c , G c ). Previously studied TW composites are used [18,21], where native wood (birch) is compared with two polymer-filled biocomposites: native birch impregnated with poly(methyl methacrylate) (Birch/PMMA), and optically transparent delignified birch impregnated with PMMA (D-Birch/PMMA).…”
