摘要： Nanocrystalline cellulose (NCC)-based supramolecular materials, a method for their preparation and their use in thermoplastic and thermoset polymer composites are disclosed. Supramolecular materials of NCC and one or two polymers are synthesized by in situ surface graft copohmerization in a multitude of solvent systems, including water. The nano-scale size supramolecular materials are engineered to have a unique combination of lower polarity and high hydrophobicity and function as copohmers for demanding pohmeric systems such as, but not limited to, polyolefins and polyesters. Nanocomposite materials of enhanced functionality and mechanical properties are produced by compounding the NCC-based supramolecular materials with polymer matrices. The supramolecular materials are used in composite development for packaging materials, structural composites for automotive and construction, as sandwiched foam composites or, combined with biocompatible polymers, in medical applications.

摘要： 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.

摘要： 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.
