A type of composite material where the matrix material and additive are held together by covalently or non-covalently bound ligands is described. A particularly useful composite material covered by the present invention is a carbon nanotube-reinforced composite material where the matrix consists of a polymer, covalently attached to a linker, where said linker is non-covalently attached to the carbon nanotube. Methods for the preparation of such composite materials are provided.

A sulfur-crosslinked rubber mixture for vehicle tires including carbon nanotubes (CNT), to a vehicle tire comprising the sulfur-crosslinked rubber mixture and to a process for producing the sulfur-crosslinked rubber mixture comprising CNT. The sulfur-crosslinked rubber mixture according to the invention is characterized in that the CNT are predispersed in at least one polyisoprene. The vehicle tire according to the invention preferably comprises the sulfur-crosslinked rubber mixture in the tread and/or a sidewall and/or a conductivity track.

A method of forming an polymer composites is disclosed herein that includes infiltrating CNT sponges with a polymer or metal to form a composite. The method uses a relatively easy, scalable, and low-cost synthesis process that makes the composites attractive as TIM. CNTs in the sponge structure are covalently bonded, resulting in a low Young's modulus while at the same time maintaining a good thermal conductivity. This strategy makes it possible to obtain both high deformability and high thermal conductivity, which are difficult to have simultaneously due to their adverse correlation.

A method of making CNT films is described in which the film is washed with a mild acid treatment. The method generates a CNT film that is not sensitive to moisture or fluctuations in moisture. The method involves the use of anionic polysaccharides or anionic glycosaminoglycans such as hyaluronic acid, sodium salt, as aqueous dispersing agents and their modification to a hydrophobic matrix after deposition. In the course of conducting the work described here, we made the surprising discovery that washing with an aqueous acidic solution resulted in a decrease in resistance through the material. The invention also includes CNT composites made by the inventive methods and a CNT composite comprising CNTs and anionic polysaccharides or anionic glycosaminoglycans further characterized by a low cationic content and a high conductivity and/or small CNT particle size as measured by SEM.

A composite structure includes a resin, a plurality of polymer nanoparticles in the resin to form a resin mixture, and a plurality of reinforcing fibers embedded within the resin mixture. At least some of the polymer nanoparticles are either fully soluble in the resin during curing or solidifying of the resin mixture to form a cured composite structure, or semi-soluble in the resin during curing or solidifying of the resin mixture to form the cured composite structure.

Nano-composite films and methods for their fabrication. The nano-composite films include a polymer matrix (e.g., polyethylene, polypropylene, or the like) and a filler capable of exfoliation such as graphene or hexagonal boron nitride (e.g., TrGO). The filler provides reinforcement, increasing tensile strength, Young's modulus, or both for the resulting nano-composite film, as compared to what it would be without the filler. The nano-composite film may have a specific tensile strength that is greater than 1 GPa/g/cm.sup.3, a specific Young's modulus that is greater than 100 GPa/g/ccm.sup.3, or both. Tensile strength and modulus values of up to 3.7 GPa/g/cm.sup.3 and 125 GPa/g/cm.sup.3, respectively, have been demonstrated. The film maybe formed by combining powdered filler and polymer matrix powder in a solvent (e.g.,decalin), high-shear extruding the resulting solution to disentangle the polymer chains and exfoliate the filler, freezing the solution to form a solid film, and then drawing the film.

A method of forming a composite material includes immersing dried plant matter into an aqueous solution containing nanoparticles and applying a magnetic field and/or an electric field to the aqueous solution. A cellular structure of the dried plant matter expands when immersed in the aqueous solution and the nanoparticles migrate into and are embedded within the expanded cellular structure of the immersed dried plant matter. The method also includes removing at least one of hemicellulose, lignin and pectins from the dried plant matter by adding a chemical additive to the aqueous solution and/or wrapping or tagging the nanoparticles with a magnetic material such as nickel.
