Micro-friction characteristics of aligned carbon nanotube film on an anodic aluminum oxide template

Aligned multiwalled carbon nanotubes (CNTs) have been obtained on an anodic aluminum oxide (AAO) template by chemical catalytic vapor deposition at 650 °C. The aligned CNTs grown out of pores of AAO membranes were uniform in diameter and about 3 μm in length. Micro-friction properties of the aligned...

Description
Summary:Aligned multiwalled carbon nanotubes (CNTs) have been obtained on an anodic aluminum oxide (AAO) template by chemical catalytic vapor deposition at 650 °C. The aligned CNTs grown out of pores of AAO membranes were uniform in diameter and about 3 μm in length. Micro-friction properties of the aligned CNT film were investigated using a friction force microscopy (FFM) and ball-on-disk tribotester under dry conditions. The FFM measurements indicated that the aligned CNT film had low friction coefficient due to the self-lubricating effect. Under a relatively low applied load, the friction coefficient of the CNT film dry sliding against a corundum ball decreased with increasing the sliding velocity, and the adhesion between the aligned CNT film and AAO template remained intact.
