Zusammenfassung:Disclosed are a method for preparing a transparent wood material by means of an organic solvent, and a transparent wood material prepared thereby and the use thereof. The specific preparation steps are as follows: first drying a veneer sample at 105 ± 5ºC, then placing same into an aqueous ethanol solution, carrying out extraction on the dried veneer sample under a condition of 85 - 95ºC, and then washing same with an aqueous ethanol solution; further carrying out retention bleaching on same using an aqueous hydrogen peroxide solution; and finally filling holes and voids of the wood material with a polymer matrix to obtain a light-permeable wood-based material. By using ethanol to dissolve lignin at a low temperature, the original structure of the wood material can be kept intact, the removed lignin is closer to the original lignin, and the prepared transparent wood material has a higher optical transmissivity.The use of a chlorine-free method to remove lignin is environmentally friendly, and, by means of dis
