Transparent wood composite (TWC) is a wood-based polymer composite with high optical transmittance and good mechanical properties, making it suitable for a wide range of applications including smart windows, energy-efficient equipment, display panels, light diffusers, and solar cell substrates. TWC shows excellent resistance to water absorption and fungal attack, making it highly reliable for moisture-sensitive and fungal-sensitive applications.
Transparent wood composite (TWC) is a novel wood-based polymer composite that combines high optical transmittance (more than 80%) with good mechanical and thermal properties. It offers numerous potential areas of applications, including smart windows, energy-efficient elements, display panels, light diffusers and substrates for solar cells. The sensitivity of TWC towards moisture and biological agents such as fungus becomes important for certain applications. In this study, TWCs were prepared using wood veneers of Populus deltoides (poplar) and Melia dubia (melia) through the process of lignin-modification bleaching and epoxy-resin infiltration. Water-absorption studies were carried out by immersing TWC specimens in deionized water for a duration of 400 h and by exposing specimens to different relative humidity (RH) conditions. The fungal resistance was evaluated by exposing specimens to a brown rot (Oligoporous placentus) and a white rot (Trametes hirsutu) fungus. Results indicated that TWC can absorb a maximum of 8% to 10% of water during a water immersion test for a period of 400 h. Exposing TWC specimens to different RH conditions resulted in no significant moisture adsorption. TWC was highly resistant to white rot and brown rot fungus.
