|Abstract:||The films tested, including bare Si, Si/octadecyltrichlorosilane (OTS), Si/APTMS or GPTMS, Si/PFPE, Si/OTS/PFPF, Si/GPTMS/PFPE, Si/polar-UHMWP E, were within the thickness ranges of a few nanometer for the SAM and ≈ 0.4-1.4 μm for the polymer films. Among all SAM, the hydrophobic layer such as GPTMS in conjunction with PFPE had good performance for wear resistance. OTS, alone or overcoated with PFPE, did not have sufficient wear life. Polymer films had much better wear lives even under more severe interfacial conditions than those of SAM. Plasma-treated PMMA film with PFPE overcoat and GPTMS/Polar-UHMWPE films have exceptional wear. Nano-lubricants were influenced by the interface bonding layer and the lubricious behavior of the top layer, e.g., PFPE. This is an abstract of a paper presented at the World Tribology Congress (Kyoto, Japan 9/6-11/2009).|
