    摘要: 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, biomass-derived silica. The tire may also contain synthetic polymers derived from biomass sugars.
