摘要： Modified nanocellulose particle include a nanocellulose particle, a binder coating the particle, and an alkyl amine affixed to the binder coating. A method of modifying nanocellulose particles includes adding a binder and a hydrophobizing agent to a slurry of nanocellulose particles in water, modifying the nanocellulose particles with the binder and hydrophobizing agent, and collecting the modified nanocellulose particles.

摘要： A method of manufacturing a polymer coated cellulose nanocrystal composite material begins with an aqueous cellulose nanocrystal (CNC) suspension mixture. The aqueous CNC suspension mixture is dried to remove the liquid solvent from the aqueous CNC suspension mixture to form a dry CNC powder. Diethylenetriamine (DETA) is combined with melted Maleated-anhydride Polypropylene (MAPP) to form a DETA-functionalized MAPP (MA) mixture. The MA mixture is cooled and pelletized to form MA pellets. The MA pellets, the dry CNC powder, and a neat polypropylene (PP) are combined to form a CNC-PP mixture. The CNC-PP mixture is compounded by melting, subsequently cooled and pelletized to form CNC-PP pellets.

摘要： A method for sealing gaps in a component including generating vapor from a liquid; directing the vapor to an exposed surface of the component, wherein the component includes a plurality of layers of an extrudate and gaps between the plurality of layers and wherein the extrudate includes an outer portion; softening the outer portion of the extrudate at the exposed surface; and filling the gaps with softened outer portion of the extrudate. An apparatus includes a heating chamber including at least one first heating element; a vapor chamber coupled to the heating chamber; a pressure regulator operatively coupled to the vapor chamber; and a nozzle coupled to the vapor chamber by a duct.
