Noncovalently functionalized highly conducting carbon nanotube films with enhanced doping stability via an amide linkage.

Creating superior electrical properties from macroscopic assembly of carbon nanotubes (CNTs) to replace metal is still an unaccomplished goal. Here we report a noncovalent functionalization method to connect individual CNTs with an electrical conductivity reaching 9150 S cm(-1) and the mechanical properties can be increased by an order of 1-2.
