Abstract MPTS/MPTES selfassembled film was fabricated on singlecrystal silicon substrates by molecular selfassembly process. Atomic force microscope (AFM), Xray photoelectron spectrometry (XPS) and contact angle measurer were used to characterize the thin films. The tribological properties of the films sliding against GCr15 steel ball were evaluated on a DFPM reciprocating friction and wear tester. The results show that the MPTS/MPTES film has excellent hydrophobic and friction and wear behavior properties compared with MPTS film and MPTES film. The cause is that the MPTS/MPTES film has big size molecule which can endow some fluidity and flexibility to the film and closepacked molecules or radicals on the bottom are rigid which can bear certain load.
