Preparation and Friction and Wear Behavior of Rare Earth Treated Carbon Nanotubes Self-assembled Composite Film

Abstract

Abstract: Rare earth (RE) treated carbon nanotubes (CNTs) composite thin films were prepared on hydroxylated glass substrates by a selfassembling process from specially formulated solution. The contact angles of distilled water on the glass selfassembled films (SAMs) and the composite film were measured to compare the surface states. The resultant composite film was characterized by means of Xray photoelectron spectroscopy (XPS). The friction and wear properties of the films sliding were evaluated on a UMT2MT reciprocating friction and wear tester. The experimental results show that CNT composite films are deposited on oxidized APTESSAM. The friction coefficient of glass substrate is reduced from 0.70 to 0.13 after the formation of CNTsSAM on its surface. The preparation of rare earth treated carbon nanotubes selfassembled composite film via selfassembly method is feasible and provides test basis for the application of CNTsSAM in the field of tribology.

Key words: rare earth, carbon nanotubes (CNTs), self-assembled film （SAM）, friction and wear behavior
