Patent ID: 7838587

Claim:
Polymer material comprising: 99 to 20 parts by weight of polymers; 0.1 to 80 parts by weight of carbon nanotubes; and 0.05 to 80 parts by weight of at least one dispersant selected from A/B/C, B/C, C/B/C block copolymers or mixtures thereof in which: each block is linked to another by means of a covalent bond or an intermediate molecule linked to one of the blocks via a covalent bond and to the other block via another covalent bond, C provides an interaction of the chemical and/or physical type with the polymer material, B is not miscible with the polymer material and with the block C, and its glass transition temperature T g is below the usage temperature of the polymer material and A is not miscible with the polymer material, the block B and the block C, and its T g or its melting point T m is above the T g of B.
