Composite materials based on carbon nanotubes and polymer matrices and processes for obtaining same

摘要

The present invention describes a composite material comprising, by weight:
- from 0.01 to 99% of carbon nanotubes (CNTs),
- of at least one block copolymer having at least one block 1 bearing ionic or ionizable functions, derived from the polymerization of at least one monomer M1 bearing these ionic or ionizable functions representing at least 10% by weight of the total weight of block 1, and optionnally a block 2 that is compatible with one polymer P1 if block 1 is not,

the copolymer being present in the material according to a CNT/copolymer ratio by mass (alpha = m(CNT)/m(copolymer)) of between 0.001 and 1000.

The composite material of the invention is used as a CNT/polymer matrix P1 compatibilizer to obtain a CNT/polymer matrix material that is homogeneous and stable.
