摘要： A flexible structure is formed by subjecting cellulose-based natural wood material to a chemical treatment that partially removes hemicellulose and lignin therefrom. The treated wood has a unique 3-D porous structure with numerous channels, excellent biodegradability and biocompatibility, and improved flexibility as compared to the natural wood. By further modifying the treated wood, the structure can be adapted to particular applications. For example, nanoparticles, nanowires, carbon nanotubes, or any other coating or material can be added to the treated wood to form a hybrid structure. In some embodiments, open lumina within the structure can be at least partially filled with a non-wood substance, such as a flexible polymer, or with entangled cellulose nanofibers. The unique architecture and superior properties of the flexible wood allow for its use in various applications, such as, but not limited to, structural materials, solar thermal devices, flexible electronics, tissue engineering, thermal management, and energy storage.

摘要： There is disclosed a method for the ammonia saturation of wood to impart flexibility thereto which includes the step of sealing the surfaces of ammonia-saturated wood with a polymeric film which has limited or no permeability to either or both ammonia and water vapor. Preferably, the polymeric film is flexible so the working of the wood product by bending, twisting, embossing, molding, etc. will not destroy the film. The polymeric film should also be soluble in a selected solvent, thereby permitting its removal after the wood has been formed in a final, desired shape to permit water vapor to re-establish crosslinking of the cellulose chains and restore its natural, rigid condition.
