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 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: 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.
