Abstract

Abstract Brushes made of carbon nanotubes have been tested by use of atomic force microscopy. Two different cantilevers were used: a silicon cantilever with a spherical tip made of SiO2 and a beryllium bronze cantilever with a tip made of steel. Sliding in the lateral direction was studied to measure the friction coefficient and to examine nanotribological properties. Nanoindentation was used to measure the pull-off force. Finally, a model of adhesion was created and experimental results were compared with it.
