Abstract Rare earth (RE) treated carbon nanotubes (CNTs) composite thin films were prepared on hydroxylated glass substrates by a selfassembling process from specially formulated solution. The contact angles of distilled water on the glass selfassembled films (SAMs) and the composite film were measured to compare the surface states. The resultant composite film was characterized by means of Xray photoelectron spectroscopy (XPS). The friction and wear properties of the films sliding were evaluated on a UMT2MT reciprocating friction and wear tester. The experimental results show that CNT composite films are deposited on oxidized APTESSAM. The friction coefficient of glass substrate is reduced from 0.70 to 0.13 after the formation of CNTsSAM on its surface. The preparation of rare earth treated carbon nanotubes selfassembled composite film via selfassembly method is feasible and provides test basis for the application of CNTsSAM in the field of tribology.
