Bio-Based Transparent Wood Composites: A New Approach and its Potentials Applications
Van Hai Le, Inha University

Wood is a natural product that is used for many applications including house, furniture, construction, pulp and papers, and so on. Wood was first converted to transparent wood in 1991 by Fink. Transparent wood has the potential for various applications including light management, solar cells, wood structure, smart building, and many others. Previous research using a polymer with the same or close refractive index to fabricate transparent wood, namely prepolymerization methyl methacrylate (PMMA), epoxy resin, polylactic acid (PLA), and so on. This report presents a transparent wood using bio-based materials of cellulose without the infiltration of polymers that have a matching refractive index as PMMA, PLA, or epoxy resin. The tensile strength of the transparent wood using CNF drastically improved leading up to 260% improvement in the longitudinal direction and around 2200% for radial direction as compared to the starting material. The Young’s modulus of the transparent wood increased from 13.5 GPa to as much as 15.3 GPa as for starting material and transparent wood, consequently. The transmittance of transparent wood reached 80%. The bio-based transparent wood shows good UV-shielding protection, and the antioxidant properties. Other advantages of the transparent wood fabricated with bio-based materials are that no toxic, erosion or harmful components are involved in the fabrication of the transparent wood. The transparent wood with high transmittance, haze, and mechanical properties has the potential for diverse applications such as food packaging, solar cells, and housing products.
