    摘要: A thermal conductive polymer molded article is formed by molding a thermotropic liquid crystalline composition comprised mainly of a thermotropic liquid crystalline polymer, wherein the thermal conductive polymer molded article is formed by applying a magnetic field or an electric field to the thermotropic liquid crystalline composition melted by heating so that the thermal conductive polymer molded article has a first thermal conductivity (λ1) higher than a second thermal conductivity (λ2) of a molded article formed by molding the thermotropic liquid crystalline polymer without the application of the field. The thermal conductive polymer molded article preferably has a first thermal conductivity (λ1) of between 0.7 and 20 W/(m·K). Preferably, the thermotropic liquid crystalline polymer comprises at least one polymer selected from (A) a wholly aromatic polyester and (B) a wholly aromatic polyester amide.

    摘要: The present invention provides an electrolyte membrane formed of an ion conductive composition. Said composition contains a liquid crystalline polymer having an ionic dissociative group. Molecular chains of the liquid crystalline polymer are orientated in a specific direction. The degree of orientation α of the liquid crystalline polymer is in a range of 0.45 or more and less than 1, as defined by equation (1) as follows, Degree of orientation α=(180−Δβ)/180  (1), wherein Δβ is a full width at half maximum of a peak in an X-ray diffraction intensity distribution pattern obtained by measuring an intensity distribution from 0 to 360 degrees in the azimuthal angle direction, at a peak scattering angle, in an X-ray diffraction image of the electrolyte membrane. Ionic conductivity in a thickness direction of the membrane is higher than the ionic conductivity in a direction parallel to a surface of the membrane. The present invention also provides a method for manufacturing an electrolyte membrane formed of an ion conductive composition.

    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.
