摘要: A biopolymer blend is provided that comprises a combination of three components: poly (butylene adipate-co-terephthalate) (PBAT); agriculture sourced polylactic acid (PLA); and engineered proteinaceous eggshell nanoparticles. The two polymer components can be present in any ratio but an approximate 70:30 ratio is preferred. The engineered proteinaceous eggshell nanoparticles are preferably about 10-25 nanometers. Also provided are methods of preparing biopolymer film and packaging components. Pelleted poly (butylene adipate-co-terephthalate) and agriculture sourced polylactic acid (PLA) are dissolved in chloroform and mixed together to form a polymer blend, and engineered proteinaceous eggshell nanoparticles are incorporated into the polymer blend, which is then extruded to create a biopolymer film or component.

摘要: Disclosed is a reinforced biodegradable polymer nanocomposite. The reinforced biodegradable polymer nanocomposite comprises a polymer matrix and functionalised graphene nanoplatelets or graphene-like material dispersed in the polymer matrix. The graphene nanoplatelets or graphene-like material are functionalized with functional groups in a manner that planar structure of the graphene nanoplatelets or graphene-like material is retained. Disclosed further is a method of manufacturing the aforementioned reinforced biodegradable polymer nanocomposite. The method comprises functionalizing graphene nanoplatelets or graphene-like material with functional groups in a manner that planar structure of the graphene nanoplatelets or graphene-like material is retained; and dispersing functionalized graphene nanoplatelets or graphene-like material in the polymer matrix to form the reinforced biodegradable polymer nanocomposite.

摘要: 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.

摘要: A method for preparing an intelligent antibacterial and antioxidative film involves preparing a PVA solution; adding nano-TiO2 to the PVA solution to obtain a PVA-TiO2 solution; determining the optimal amount of nano-TiO2; preparing a PSPC solution; preparing a PSPC-TiO2-PVA solution; and producing a PSPC/TiO2/PVA film. The film has better mechanical performance than saccharide and protein films. Shelf life of food is prolonged as the film possesses antibacterial and antioxidative properties. Furthermore, the film shows different colors in various pH environments. The film has a wide range of applications in food packaging owing to the integration of color development and antibacterial and antioxidative properties.

摘要: An object of the present invention is to produce composite resin particles in which the original physical properties of PTFE derived from fine powder are maintained, and the present invention provides a method for producing composite resin particles, wherein the method includes: a first step in which fine powder containing polytetrafluoroethylene obtained by emulsion polymerization is pulverized in the presence of a ketone-based solvent; a second step in which the pulverized fine powder and a carbon nanomaterial are dispersed in the ketone-based solvent to produce a composite resin particles dispersion; a third step in which the composite resin particles are produced by removing the ketone-based solvent from the composite resin particle dispersion; and wherein the fine powder is pulverized so as to have an average particle diameter of 50 μm or less, and a temperature of the ketone-based solvent used in the first step is set to 20° C. or less.
