Currently, modified wood (MW) has emerged as an eco-friendly substrate for optoelectronics, energy storage, and biomedical devices. The delignified wood can be infiltrated with a refractive index-matched polymer to fill in the lumen pores, and the resultant material is transparent wood (TW) after drying. We plan to impregnate the delignified wood with a bio-compatible and bio-degradable polymer, poly-albumen (PA), to create TW. We hypothesize that PA will create durable TW and be further modified to fire-retardant and electrically conducting wood. The three objectives are: i) creating biocompatible TW by infiltrating delignified wood with PA, ii) modify TW with a metal-organic framework (MOF) to furnish fire-retardancy, iii) and create a TW with electrical conductivity by incorporating silver nanowires (AgNWs). Such MW would have tremendous potential in optoelectronics, energy storage, and biosensors. We characterize samples with FTIR, Raman, UV-vis DRS, XRD, TGA, and SEM.
