A hybrid polymer-matrix composite is described, containing between 10.0% and 45.0% by weight of cellulosic fiber up to 3.0 mm long and with a maximum moisture content of 5.0%; between 5.0% and 40.0% by weight of synthetic fiber up to 4.0 mm long and compatibilizing additives, said constituents being homogenized directly in the twin-screw extruder, with each reinforcing fiber entering via a specific feeder, to be adjusted to the temperature and shearing applied to the reinforcing fibers, guaranteeing the correct dispersion of the fiber for encapsulation by the polymer matrix, optimizing interface interactions and perfect homogenization.

The invention relates to the technical field of composites, in particular to a high-toughness and high-strength wood-plastic composite and a preparation method thereof. The wood-plastic composite is prepared from the following preparation raw materials in parts by mass: 30-50 parts of wood flour, 11-20 parts of high molecular weight polyethylene, 30-52 parts of polypropylene and 2-10 parts of an interface modifier. Polypropylene is used as a main component of a plastic matrix; high molecular weight polyethylene is used as a secondary component of the plastic matrix and has a toughening effect; wood flour is used as a filler to improve the strength of the wood-plastic composite; the interface modifier can improve the interface bonding between the wood flour and the plastic matrix, and all components have a synergistic effect, so that the obtained wood-plastic composite has high toughness and high strength.

Provided is a method of preparing a superabsorbent polymer. More particularly, provided is a method of preparing a superabsorbent polymer, the method capable of preparing the superabsorbent polymer maintaining excellent basic absorption performances such as centrifugal retention capacity, absorbency under load, etc. while also exhibiting an improved absorption rate.

A microfibrillated cellulose-loaded foam is indicated, comprising microfibrillated cellulose, at least one thickening agent and/or at least one adhesive biopolymer. Furthermore, a method for producing such a microfibrillated cellulose-loaded foam and a use of such a foam are provided.

The present invention provides methods for preparing the nut waste pot composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.

The presently disclosed subject matter is generally directed to a packaging film constructed from water-dispersible and/or biodegradable compositions. Particularly, the disclosed film comprises a first layer constructed from one or more water-dispersible materials, such as water-dispersible paper. The film further comprises a second layer constructed from one or more biodegradable materials, such as poly(hydroxyalkanoate). The first and second layers can be constructed to form a packaging material used to enclose a wide variety of products, including liquids and moisture-sensitive solids. Advantageously, the disclosed film (and associated packaging materials) are dissolvable in water and/or biodegrade when exposed to landfill conditions and/or water.

The present invention provides methods for preparing the nut waste pot composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.

Disclosed herein is a method for preparing an antibacterial bio-filler for plastics and an antibacterial bio-filler for plastics, prepared thereby. More specifically a method for preparing an oleophilic antibacterial bio-filler for plastics from hydrophilic lignocellulosic biomass and an antibacterial bio-filler for plastics prepared thereby are provided.

The present invention provides a biomimetic composite material, a nacreous layer-mimetic material, a biomimetic nacre material and preparation methods thereof. The biomimetic composite material comprises multiple composite film formed from biomass fibers and an inorganic nanomaterial, wherein an organic polymer material is arranged between the multiple composite film layers or in the composite base body. The invention combines a high-mechanical-performance shellfish structure with a wood fiberboard to overcome the original defects of the fiberboard, improve the fiberboard performances and endow it with new special performances, so that the prepared material has dual functions of the fiberboard and the nanomaterial at the same time.

The disclosure is directed to methods of manufacturing protective packaging materials, as well as the protective packaging materials produced using the disclosed methods. These packaging materials can be biodegradable, compostable, and/or recyclable.
