The present invention relates to (1) 99 to 20 parts by weight of one or more polymers, (2) 0.1 to 80 parts by weight of carbon nanotubes, and (3) 0.05 to 80 parts by weight of A / B / C. A polymer material in which carbon nanotubes are dispersed in a polymer material, comprising at least one dispersant selected from B / C and / or C / B / C block copolymers. (A) Each block is bonded to each other by a covalent bond or bonded to one of the blocks through a covalent bond and to each other through an intermediate molecule bonded to the other block through another covalent bond. (B) C interacts chemically and / or physically with the polymer material, (c) B is immiscible with the polymer material and the C block, and its glass transition temperature Tg is the use of the polymer material Below the temperature, (d) A is immiscible with the polymeric material, B block and C block, and its T g or its melting point T m is higher than the T g of B. |
