    Abstract: An oleophilic and hydrophobic nanocellulose material is disclosed herein, for nanocellulose sponges and other applications. The oleophilic and hydrophobic nanocellulose material comprises lignin-coated cellulose nanofibrils and/or lignin-coated cellulose nanocrystals. In various embodiments, the nanocellulose material is in the form of a 2D coating or layer, or a 3D object (e.g., foam or aerogel). The nanocellulose material may be disposed onto a scaffold. A process is provided for producing an oleophilic and hydrophobic nanocellulose object, comprising fractionating a biomass feedstock with an acid, a solvent for lignin, and water, to generate cellulose-rich solids and a lignin-containing liquor; mechanically treating the cellulose-rich solids to form cellulose fibrils and/or cellulose crystals; generating a nanocellulose object from the intermediate nanocellulose material; exposing the nanocellulose object to the lignin-containing liquor to allow lignin to deposit onto a surface of the nanocellulose object; and recovering the oleophilic and hydrophobic nanocellulose object.

    Abstract: Cellulose materials and methods of making the cellulose materials are described herein. The method can include contacting a cotton fabric with an oxidizing system to obtain an oxidized cotton material and processing the oxidized cotton material to form the cellulose material. The oxidizing system can include an aqueous mixture of a N-oxyl compound and a hypochlorite compound. During oxidation, the pH of the aqueous mixture can be maintained at from 8.5 to 11. Cellulose products can be formed from the cellulose materials. For example, the cellulose products can be used to form a packaging material, a biomedical device or implant, a drug delivery material, a fiber, a textile material, a template for electronic components, or a separation membrane. Methods of making the cellulose product include dissolving or suspending an active ingredient in a medium comprising the cellulose material.
