The present invention relates to polyamide (A) / polyolefin (B) blends containing carbon nanotubes.n n n The invention also relates to a structure comprising at least one of said blending layers and optionally at least one of another layer of material. The structure may be in the form of bottles, tanks, containers, hoses, pipes and any kind of container. The structure can be manufactured using standard techniques for thermoplastics such as injection molding, extrusion-blow molding and coextrusion.n n n According to one embodiment, the present invention relates to a multilayer tube containing the following in the radial direction from outside to inside:n n n Outer layer (1) formed of a polyamide selected from PA-11 and PA-12;n n n A layer 2 formed of a tie;n n n Optional layer (3) formed of EVOH;n n n Any connector layer (which is absent if layer 3 is absent);n n n An inner layer 4 formed of a polyamide (A) / polyolefin (B) blend having a polyamide matrix and containing carbon nanotubes;n n n The layers are continuous and adhesive to each other at each contact area. |
