Abstract: The present disclosure relates to surface modified nanocrystalline cellulose (NCC) prepared by chemical modification of NCC as well as its use thereof, including as carrier of particular chemical compounds. The surface of nanocrystalline cellulose (NCC) was modified with chitosan oligosaccharide (CSos) by selectively oxidizing the primary alcohol moieties of NCC followed by coupling of the amino groups of CSos to the oxidized NCC to provide the desired material (NCC-CSos).

Abstract: This invention describes development of a novel flexible film comprising nanocrystalline cellulose (NCC), or cellulose nanocrystals (CNC), and a controlled amount of a suitable zwitterionic (amphoteric) surfactant. The films are iridescent and have a high level of structural integrity, where mechanical properties can be engineered to suit the end applications. Flexible NCC films can be used in a multitude of applications, for instance, electrostatic shielding, gas barrier, hard coatings, printing.

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.

Abstract: The disclosure relates to a novel process for functionalizing NCC, a method for producing amine-cured epoxy-based nanocomposites through the use of said functionalized NCC, and nanocomposites thereof. The process for functionalizating NCC comprises providing a mixture of NCC and one or more monomers. The mixture is suitable for free radical polymerization and the monomer is cross-linkable with epoxy and is aqueous soluble. The polymerization takes place in the presence of a free radical initiator and oxygen is purged from the mixture and the initiator solution. The epoxy-based nanocomposite is produced by mixing the funtionalized NCC with an amine-curable epoxy resin and a hardener, in a solvent, and allowing the mixture to cure.

Abstract: A redispersible, chemically modified cellulose nanocrystal comprising an ionic adduct of a negative ion of sulfate, phosphate half-ester, carboxylic acid or mixtures thereof and a positively charged protonated amine compound. The modified cellulose nanocrystals are readily redispersible in a variety of media and produce stable emulsions. The modified cellulose nanocrystals are produced by adding to an aqueous suspension of acidic cellulose nanocrystals, a quantity of the amine compound to increase the pH of the suspension to about below the pKa of said amine, mixing and drying the resulting suspension to produce the redispersible CNC.
