The present invention relates to a conductive carbon nanotube-polymer composite, comprising carbon nanotubes, and a mixture of polymers in a form of coalesced polymer particles, wherein the mixture of polymer particles in their non coalesced form is defined by the presence of at least two population of polymer particles having a size distribution which is at least bimodal.

Conductive carbon nanotube-polymer composite

The invention relates to a polymer material comprising 99 to 20 parts by weight of polymer(s), 0.1 to 80 parts by weight of carbon nanotubes, and 0.05 to 80 parts by weight of at least one type of dispersant selected from A-B-C, B-C and/or C-B-C block copolymers, wherein each block is bonded to the other by means of a covalent bond, C is a chemical and/or physical interaction with the polymer material and in preferably is miscible therwith, B is not miscible with the polymer material and with the block B and the glass transition temperature thereof. Tis less than the polymer material use temperature, A is not miscible with the polymer material and with the blocks B and the block C and the Tor the fusion temperature Tf is greater than the Tof B.

Polymer materials containing dispersed carbon nanotubes

The present invention describes linear or star block copolymers, their process of preparation and their use in adhesive compositions, in particular as pressure-sensitive adhesive. The copolymers of the invention are prepared by controlled radical polymerization by nitroxides; they exhibit at least one soft block with a Tg of less than 0&#xb0; C. and at least one hard block with a Tg of greater than ambient temperature.
