Abstract: The disclosure provides redispersible CNC. The CNC disclosed herein is redispersible in non-polar and polar organic solvents as well as polar and non-polar polymers such as polyethylene or polypropylene. The disclosure surprisingly also provides redispersible CNC bearing improved redispersion in aqueous systems and most particularly in high ionic strength aqueous systems which usually require significant mixing energy to achieve dispersion.

Abstract: A process for preparing polyurethane composites includes (i) providing a dispersion of nanocrystalline cellulose in (a) one or more polyols, (b) one or more isocyanates, or (c) one or more polyols and one or more isocyanate, mixed together; wherein the amount of water in the nanocrystalline cellulose is less than about 1% w/w; (ii) mixing the dispersion of (i)(a) with an isocyanate or (i)(b) with a polyol and a catalyst to allow polymerization; or mixing the dispersion of (i)(c) and a catalyst to allow polymerization; and (iii) isolating the polyurethane composite. A method for improving properties of polyurethanes includes dispersing nanocrystalline cellulose into one or both parts of a two part polyol/isocyanate precursors prior to allowing polymerization of the precursors, wherein the amount of water in the nanocrystalline cellulose is less than about 1% w/w; mixing the dispersion with a catalyst; and polymerizing the precursors to provide the polyurethane.

Abstract: The present disclosure relates to a process for preparing coated cellulose nanocrystals (CNCs) and relates as well to coated cellulose nanocrystals (CNCs) obtainable by the process described herein. These new CNC hybrid nanomaterials are expected to be useful, for example, for the conjugation and electrostatic complexation with various functional moieties such as free metal ions, carboxylic acids, and epoxy and aldehyde derivatives. The disclosure further relates to a method to fabricate N-doped carbon nanomaterial from the coated CNCs.
