摘要： A graphene composite fiber includes graphene sheets and a polymer for aggregating the graphene sheets together. The polymer includes either or both of a hyperbranched polymer and polyvinyl alcohol. The graphene sheets and the polymer are stacked on each other to form a layered structure, and the graphene sheets are regularly arranged along an axial direction of the graphene composite fiber. In a production method of the graphene composite fiber, a graphene oxide is used as a raw material, which significantly improves tensile strength of the graphene composite fiber. Addition of the polymer provides good tenacity for the composite fiber. In a spinning process, rotated coagulant is used to increase a tensile force of a gelatinous fiber, so that the gelatinous fiber has high orientation and tacticity, thereby significantly improving strength of an obtained solid fiber. The final reduction process restores electrical conductivity of a graphene fairly well.

摘要： The present invention provides an oriented flexible heat-conducting material, where main ingredients of the oriented flexible heat-conducting material are silicone rubber and anisotropic heat-conducting filler. Multiple continuous heat-conducting paths that are parallel to each other are formed in the oriented flexible heat-conducting material, and the heat-conducting paths are formed by continuously arranging the anisotropic heat-conducting filler, filled in the silicone rubber, in lines in a heat-conducting path direction. The oriented flexible heat-conducting material has a desirable heat-conducting property in a specific direction and has desirable flexibility, can be in desirable contact with an interface to produce quite low interface thermal resistance, and can greatly improve a heat dissipation effect.

摘要： A thermal interface material, a method for preparing a thermal interface material, a thermally conductive pad, and a heat dissipation system are provided. In one example, the thermal interface material includes a metal zirconium coil and carbon nanotube arrays, where the metal zirconium coil has a first surface and a second surface that is opposite to the first surface. The carbon nanotubes in the carbon nanotube arrays are distributed on the first surface and the second surface. Further, the first surface and the second surface of the metal zirconium coil include exposed metal zirconium. Therefore, interface thermal resistance of the thermal interface material is reduced, and a heat conducting property of the thermal interface material is improved.
