Patent number: 11306206Abstract: A composite and method for producing the composite by incorporating wood or wood pulp fibres with a suitable thermoplastic polymer and coupling agent are described. Homogeneous, void-free transparent/translucent thermoplastic materials in the form of pellets, films or three-dimensional moldable products are produced. The wood pulp fibres can be discrete natural fibres, and flexible assemblies of nano to micro elements, e.g., assemblies of aggregated carbon nanotubes. It is also possible to use our vacuum-assisted co-extrusion process to produce hybrid composites comprising the wood pulp fibre and a further rigid fibre, like glass or carbon fibres, and a flexible fibre or fibrillar network, like cellulose fibres or cellulose filaments. The thermoplastic resin can be, but not limited to, polyolefins, like polypropylene or polyethylene, or polyesters, like polylactic acid, or co-polymers, like acrylonitrile-butadiene-styrene terpolymer.Type: GrantFiled: July 25, 2017Date of Patent: April 19, 2022Assignee: FPInnovationsInventors: Wadood Yasser Hamad, Shunxing Su, Norman Roberts, Otman Oulanti, Michelle Agnes Ricard, Chuanwei Miao

Patent number: 9751969Abstract: 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.Type: GrantFiled: September 12, 2012Date of Patent: September 5, 2017Assignee: CELLUFORCE INC.Inventors: Wadood Y.

Patent number: 9624330Abstract: 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.Type: GrantFiled: November 12, 2013Date of Patent: April 18, 2017Assignee: CELLUFORCE INC.Inventors: Wadood Yasser Hamad, Shunxing Su

Patent number: 8828434Abstract: Nanocrystalline cellulose (NCC) is employed as the cross-linker and reinforcement domain for developing nanocomposite hydrogels possessing high strength and improved diffusion property; the resulting nanocomposite hydrogels are shown to have high mechanical properties, reversible swelling ability, and are biodegradable and biocompatible; the approach relies on free radical polymerization to form the hydrogels using a variety of hydrophilic vinyl monomers. These hydrogels are suitable for developing highly absorbent hygiene products, as well as for applications in medicine, engineering materials and sensors.Type: GrantFiled: January 20, 2011Date of Patent: September 9, 2014Assignee: FPInnovationsInventors: Shunxing Su, Wadood Y.

Patent number: 8349948Abstract: A green approach for the development of nanocomposite materials comprising nanocrystalline cellulose (NCC) and appropriate vinyl polymers is conceived. The approach deals with the in-situ graft co-polymerization of hydrophobic vinyl monomers, such as vinyl acetate and methyl methacrylate, onto the NCC surface in an aqueous medium. The resulting material is significantly more hydrophobic and thermally stable than the starting NCC. The nanocomposite material can be suspended in appropriate solvents, dried and molded with other materials using conventional polymer processing techniques to develop yet new materials with new characteristics. These nanocomposites have wide ranging applications from industrial to medical use.Type: GrantFiled: February 1, 2011Date of Patent: January 8, 2013Assignee: FPInnovationsInventors: Wadood Y.
