Functionalization of cellulose with lignin to produce high-value products

The present invention concerns a process for the covalent attachment of lignin to cellulose in aqueous solutions, which process is characterized by preparing an aqueous mixture of lignin particles modified with tall oil fatty acids (TOFA), and reacting these TOFA-modified lignin particles with cellulose particles. The obtained modified cellulose particles are biodegradable, and have antimicrobial properties, whereby they are suitable for use in antibacterial textile surfaces (sportswear, medical textiles), tissue adhesives and as porous carriers in drug delivery. Further, the material is useful in high-volume products, such as adhesives and dispersants.

AUTOMOTIVE TIRES CONTAINING HYDROPHOBIC NANOCELLULOSE
20180327569 · 2018-11-15 ·

The present invention provides an automotive tire containing from 0.1 wt % to 50 wt % hydrophobic nanocellulose. Hydrophobic nanocellulose may include lignin-coated nanocellulose and/or a chemically modified surface to increase hydrophobicity. The nanocellulose may include cellulose nanofibrils and/or cellulose nanocrystals. The nanocellulose may be introduced into tire components such as inner liner, body ply, sidewall, beads, apex, belts, treads, cushion gum, and textile fabric. The nanocellulose may be obtained from a biomass-fractionation process utilizing an acid catalyst, a solvent for lignin, and water to generate a lignin-containing nanocellulose precursor, followed by mechanical treatment of the nanocellulose precursor to produce the nanocellulose. For example, the nanocellulose may be obtained from the AVAP process. The tire may further include one or more additional components derived from lignocellulosic biomass. For example, the tire may contain lignin-derived carbon black, lignin-derived antioxidants, or biomass-derived silica. The tire may also contain synthetic polymers derived from biomass sugars.
