The present disclosure describes a treated cellulosic material comprising: a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising: a polymer comprising an olefin-carboxylic acid copolymer; and a modifying agent comprising a polyamine having greater than or equal to 2 amine groups, wherein the modifying agent crosslinks at least a portion of the polymer.

In some examples, one or more metal-containing catalysts and one or more waxes can be mixed or otherwise combined to produce an encapsulated catalyst composition. The wax can be at least partially coated on the metal-containing catalyst. A mixture of water and the wax can be agitated or otherwise mixed, and the metal-containing catalyst can be added to or otherwise combined with the water and wax mixture to produce a wax emulsified catalyst. A plurality of lignocellulose substrates, one or more oxidants, and the encapsulated catalyst composition can be mixed or otherwise combined to produce a lignocellulose binder mixture. The lignocellulose binder mixture can be heated to produce a composite product.

Methods of treating wood and wood products include irradiating untreated wood having a first molecular weight with ionizing radiation to cause an increase in the molecular weight of a cellulosic component of the wood to a second, relatively higher molecular weight.

Aspects of the invention include color change compositions having a color former and color developer composition that transitions from a first color state to a second color state upon application of an applied stimulus and an amount of a copolymer sufficient to eliminate background color of the color former and color developer composition during transition from the first color state to the second color state. Methods for preparing and devices employing the color change compositions of the invention are also described.

A method for manufacturing bamboo plastic composite material having steps of cutting multiple bamboo stalks into multiple bamboo pieces and grinding the bamboo pieces to form multiple bamboo powders; cleaning the bamboo powders; drying the bamboo powers; modifying the bamboo powders; mixing multiple raw materials to form a bamboo plastic composite material with a composition of PVC 10 to 20 wt %; vinyl chloride/vinyl acetate (VC/VAC) copolymer 10 to 30 wt %; styrene-acrylonitrile copolymer (SAN) 1 to 5 wt %; chlorinated polyethylene (CPE) 1 to 5 wt %; the bamboo powders 10 to 40 wt %; inorganic filler 10 to 40 wt %; internal lubricant 0.1 to 1 wt %; external lubricant 0.1 to 1 wt %; and heat stabilizer 1 to 5 wt %; and forming and molding the bamboo plastic composite material.

The present invention relates to a method of plasticizing and densifying hydrophilic polymeric biomaterial, said hydrophilic polymeric biomaterial having at least one surface, comprising the steps of softening the surface of the hydrophilic polymeric biomaterial to be compressed; compressing the hydrophilic polymeric biomaterial by applying an elevated pressure onto the softened surface of said hydrophilic polymeric biomaterial at an elevated temperature for a predetermined period of time; decreasing the temperature and thereafter the pressure applied to the hydrophilic polymeric biomaterial; wherein a plasticizing liquid is added to said surface of the hydrophilic polymeric biomaterial to be densified, the plasticizing liquid being a non-imidazolium-based ionic liquid (IL), an organic superbase or a Deep Eutectic Solvent (DES).

A mono-extruded hemp composite board (EHB) is provided. By combining hemp feedstocks with virgin and/or recycled binder materials and subsequently extruding them into an extrudate sheet, an environmentally friendly alternative to tradition construction materials is created. Secondary feedstocks and waste products from other production streams may be added during the extrusion process to enhance the physical characteristics of the extrudate sheet in addition to reducing the raw material costs and creating a more environmentally friendly construction material. The extrudate sheet produced using such materials is structurally superior to traditional construction materials due to the structural characteristics of dispersed hemp feedstocks; the complete encapsulation of hemp feedstocks in the binder material; and the lower hygroscopic and higher pest and mold resistance properties of hemp feedstocks. A downstream extrusion arrangement may be used to pattern the extrudate sheet and/or create molded shapes that are difficult to achieve in traditional construction materials, increasing the customization potential of final EHB products relative to traditional construction materials.

The present disclosure relates to a method for preparing a scratch-resistant bio-additive for plastics and a scratch-resistant additive for plastics prepared thereby and, more specifically, to a method for preparing a scratch-resistant bio-additive for plastics, which is oleophilic from hydrophilic lignocellulosic biomass, and to a scratch-resistant bio-additive for plastics prepared thereby.

The present invention relates to a method of producing wooden components, wherein in the method a first wooden slat is provided with an adhesive at at least one of its planar broad sides and/or at at least one of its narrow sides and the first wooden slat is glued to a second wooden slat to form a block of a plurality of wooden slats, wherein at least the first wooden slat is in a wet state during the gluing.

A bio-derived wearable film includes an acid-hydrolyzed palm stem pith, a starch, a cellulose, a synthetic polymer, a plant hydrogel, glycerin, and a dye, and a method of producing the bio-derived wearable film.
