Abstract: This disclosure provides a polymer composite including a polymer, nanocellulose, and a compatibilizer, wherein the nanocellulose comprises cellulose nanocrystals and/or cellulose nanofibrils, and wherein the compatibilizer comprises a maleated polymer. In some embodiments, the nanocellulose includes lignin-coated nanocellulose. The polymer may be selected from polyethylene, polypropylene, polystyrene, polylactide, or poly(ethylene terephthalate). The maleated polymer may be selected from maleated polyethylene, maleated polypropylene, maleated polystyrene, maleated polylactide, or maleated poly(ethylene terephthalate. Other variations provide a process for compatibilizing a polymer with nanocellulose, comprising: providing a polymer; providing nanocellulose comprising cellulose nanocrystals and/or cellulose nanofibrils; providing a maleated polymer; and combining the polymer, the nanocellulose, and the maleated polymer, wherein the maleated polymer functions as a compatibilizer between the polymer and the nanocellulose.

Abstract: A new polystyrene-nanocellulose composite material is disclosed. The composite may contain about 0.01 wt % to about 10 wt %, such as about 0.1 wt % to about 2 wt % of nanocellulose. In some embodiments, the nanocellulose is lignin-coated nanocellulose, such as lignin-coated nanocellulose is obtained from an AVAP® biomass-fractionation process. The nanocellulose may include cellulose nanocrystals and/or cellulose nanofibrils. The polymer composite may be in the form of a polymer melt, or a finished polymer material. The composite is characterized by IZOD impact resistance that is at least 50% (such as 75% or more) higher compared to the polystyrene alone.
