This invention relates to a composite material which is a copolymer of at least (i) a functionalised carbon nanoparticle, (ii) a polyol, (iii) a compound comprising at least two isocyanate groups, wherein the functionalised carbon nanoparticle and the polyol are covalently bonded by a urethane and optionally a urea and/or an amide linkage, and a process for producing the same. Such composite materials are suitable for use in moulded articles for implantation within a mammal.

Provided is a nanosubstance-containing composition which exhibits excellent heat resistance in cases where a thermoplastic resin or a rubber is contained therein, while exhibiting high toughness in cases where a thermosetting resin is contained therein. A nanosubstance-containing composition according to the present invention contains (a) at least one component selected from the group consisting of thermoplastic resins, thermosetting resins and rubbers, (b) a compound having a reactive functional group and (c) a nanosubstance.

A composite resin material particle of the present invention includes: a resin material particle that is a material for producing a resin molding product; and a conductive nano-material, wherein a dispersion mixing layer, which is obtained by dispersedly mixing the conductive nano-material from the surface to the inside of the resin material particle, is formed over all of the surface or at least a part of the surface of the resin material particle, the conductive nano-material is dispersedly mixed within a resin material of the resin material particle in the dispersion mixing layer, and the whole of the dispersion mixing layer forms a conductive layer.

The present disclosure relates to a carbon fiber composition and a fabrication method for high-performance carbon fiber using the same. The method can fabricate high-performance carbon fiber (or graphite fiber) with lowering a graphitization temperature by using graphene carbon fiber composition including nano-sized graphene.
