A method for producing a wood sheet that is between 0.6 and 0.8 mm thick, includes covering both surfaces with a matte crystal clear polyester film that is between 70 and 80 micrometres thick joined by thermopressing to the wood sheet. The wood sheet is sanded between the method steps to a thickness ranging from 0.6 to 0.8 mm, a matte polyester film with a thickness ranging from 70 to 80 micrometres is applied, they are then thermopressed at a controlled temperature and speed, and the wood sheet covered with the plastic material film is cold-pressed. The present invention also relates to a translucent wood sheet which allows illumination lamps having unique configurations to be produced.

According to an example aspect of the present invention, there is provided a method of joining objects of hydrophilic polymeric biomaterials. In the method, an ionic liquid is applied onto the surfaces of the objects; the surfaces are pressed together; and the ionic liquid is removed. The method produces a product that can consist to 100% of biomaterial, with no synthetic polymer or chemicals remaining in the product.

A floor panel with a substrate and a decorative layer of wood veneer with a thickness of 1 millimeter or less and provided on the substrate. The decorative layer is provided on the substrate by means of a glue layer which is situated between the substrate and the decorative layer. The glue layer comprises hard particles with an average particle size which is at least one third of the thickness of the wood veneer. Methods for manufacturing such floor panels are provided.

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.

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.
