    摘要: A heat radiation member including a thermal diffusion sheet; and a thermally conductive polymer layer provided on at least a part of the thermal diffusion sheet. Thermal conductivity of the thermally conductive polymer layer in a thickness direction of the layer is higher than thermal conductivity of the thermally conductive polymer layer in a direction parallel to the surface of the layer. The heat radiation member is formed by joining an independently formed thermally conductive layer including a thermally conductive filler onto the thermal diffusion sheet. The thermally conductive filler are oriented in a specific direction. Alternatively, the heat radiation member is formed by placing a thermally conductive polymer composition containing a thermal conductive filler containing a thermally conductive filler onto the thermal diffusion sheet, orienting the thermally conductive filler in a specific direction, and curing the thermally conductive polymer composition while the orientation is maintained.

    摘要: A method of manufacturing a heat conductive molded part having determined heat conductivity properties is provided. The method includes providing a polymer composition containing boron nitride powder. A magnetic field is impressed to the polymer composition containing boron nitride powder, field orienting the boron nitride powder in the polymer composition to a fixed direction. The polymer composition is set containing boron nitride powder with the boron nitride powder oriented in the polymer composition to the fixed direction. The polymer composition may also be provided containing a solvent. The solvent is removed after field orienting the boron nitride powder in the polymer composition to the fixed direction The composition is then set with the field oriented boron nitride powder after having removed the solvent.

    摘要: Graphitized carbon powder are produced by carbonizing and expanding a pitch by heating to form carbonaceous foam and by graphitizing before pulverizing or graphitizing after pulverizing the carbonaceous foam. The resultant graphitized carbon powders have an interplanar spacing (d002) of graphite planes of less than 0.3370 nm. The powders preferably have an average particle size of from 2 to 200 &mgr;m. A thermally conductive composition includes the graphitized carbon powders in a matrix. The content of the powders is preferably 1 to 800 parts by weight relative to 100 parts by weight of the matrix. Thus, the graphitized carbon powders that have excellent thermal conductivity and a thermally conductive composition including such powders are provided.

    摘要: A thermally conductive molded article is produced by molding a conductive composition into a predetermined shape. The composition includes a polymer matrix and carbon powders. The carbon powders are obtained by graphitizing a polymeric material that has an aromatic ring on its main chain by heating. The carbon powders are aligned in a certain direction in the polymer matrix. Thus, the molded article can be produced easily and effectively that has excellent thermal conductivity in a given direction and that is suitable for use as a heat radiator, heat transfer member, or a component thereof in electronic hardware.
