Mechanical and tribological behaviour of carbon nanotube brushes
-
Dariusz Jarzącbek
Abstract
Carbon nanotube brushes of micrometre range height were deposited on a silicon substrate and tested by use of atomic force microscopy. The cantilever's tips were made of silicon or steel. Firstly, the effect of the structure of carbon nanotubes on indentation (mechanical behaviour) in normal direction to the substrate was studied. Moreover, to examine nanotribological properties, sliding in the lateral direction to the substrate was studied. We also studied how the resonance frequency of vibration of one kind of microfork changes with the depth, to examine the connection between friction force and depth of the measurement. Finally, a mathematical model of the mechanical and tribological properties of carbon nanotube brushes was elaborated.
