Abstract

The friction response of a vertically aligned carbon-nanotube (VACNT) film against gold tips was investigated. The film was 6 micrometer thick and the applied force was smaller then 5 micro-newton. The friction properties of the VACNT film satisfies the Amontons-coulomb friction law except for extreme high friction. The result shows that the tip showed that low-angle directions of repulsive forces due to bending of the carbon nanotubes are required to explain the high friction coefficients.
