The present disclosure relates generally to polyurethane matrix composite materials, for example, suitable for making an exterior cladding product for houses and other buildings. The present disclosure relates more particularly to a polymer matrix composite material including a polyurethane matrix and an inorganic filler in a range from 45% to 85% by weight of the composite material. The inorganic filler includes a first substance from the group consisting of calcium carbonate, sand, talc, kaolin clay, dolomite, feldspar and mica and any mixture thereof, and fly ash, and/or an iron oxide in a range from 0.5% to 7% by weight of the inorganic filler.

The present disclosure relates to methods and systems for making thermoplastic resin materials and composite resin systems and materials made from the thermoplastic resins, by seeding one melted thermoplastic material with a second thermoplastic material in a crystalline state that comprises an amount of ferromagnetic material.

An adhesive composition degradable by dielectric heating. The adhesive composition comprises a thermosetting polymer and a material sensitive to dielectric heating. The material sensitive to dielectric heating is selected from any one or more of hollow nanospheres, nanotubes, nanorods, nanofibres, nanosheets, graphene, graphene derivatives, nano/micro hybrids and mixtures of two or more nanoscale particles. The adhesive composition may be particularly useful in the assembly and disassembly of parts, particularly parts which have complicated and/or blocked joined surfaces. A method of joining at least two parts of an article together and a method of disassembling at least two parts of an article, using the adhesive composition are also provided. The adhesive composition may provide a reworkable nanocomposite adhesive. The adhesive composition maybe used to reversibly bond a biomedical or dental implant to a part of a human or animal body.

Provided are a nanoparticle-polymer fluorescent composite and a method of preparing the same. The method includes preparing magnetite (Fe.sub.3O.sub.4)nanoparticles, mixing the magnetite (Fe.sub.3O.sub.4) nanoparticles, an organic polymer having an aliphatic carbon chain, and a solvent for dissolving the organic polymer to prepare a preliminary composite and drying the preliminary composite to form a nanoparticle polymer composite, and irradiating a pulse laser to the nanoparticle polymer composite to change the magnetite (Fe.sub.3O.sub.4) nanoparticles to Wustite nanoparticles and providing conjugated polymer characteristics to the organic polymer.

A carbon nanotube (CNT)/polymer film or CNT/polymer composite structure containing CNTs, arranged uniformly in a randomly oriented distribution in the polymer matrix. The CNT sheet is manufactured by applying a highly dispersed CNT-polymer-solvent suspension, mixed using ultrasonication, over a carrier, using a coating process, and drying to form the CNT/polymer film. The CNT film is useful in making CNT composite laminates and structures having utility for electro-thermal heating, deicing, shielding for wire & cable, thermal interface pads, energy storage, heat dissipation, conductive composites, antennas, reflectors, and electromagnetic environmental effects (E3), such as lightning strike protection, EMP protection, directed energy protection, and EMI shielding in a variety of form factors such as sheets, roll stocks, and tapes.

The present invention relates to a process for producing nanocapsules employable as thermo latent polymerization catalysts, in particular for the polymerization of polyurethanes, by means of a high shear process, wherein the process comprises: (i) emulsifying a first reaction mixture (a) in a continuous aqueous phase comprising at least one stabilizer; (ii) emulsifying a second reaction mixture (b) in a continuous aqueous phase comprising at least one stabilizer; (iii) combining the first reaction to the nanocapsules produced by means of the described processes, to the use thereof, and to agents which contain these nanocapsules.

Disclosed is a non-destructive universal method of functionalization of graphitic carbonaceous materials that enables their alignment, cross-linking, and effective integration into composite materials.

The present application provides a composite material and a method for producing the same. The present application can provide a composite material having excellent other necessary properties such as impact resistance or processability, as well as excellent heat conduction characteristics as a tight heat transfer network is formed therein by an anisotropic heat-conductive filler.
