Abstract: The invention concerns a composition comprising a first polyamide, a second polyamide, different from the first polyamide, and 0.1 to 5% by weight of carbonaceous nanofillers, in which: a) the first polyamide comprises a unit derived from the condensation of meta-xylylene diamine or from a mixture of meta-xylylene diamine and para-xylylene diamine with sebacic acid, said first polyamide having a melting temperature Tf1; and b) the second polyamide has a melting temperature Tf2 higher than or equal to Tf1−40° C. The invention also relates to a method for producing said composition and the use thereof for producing various items.
