中文摘要	Hybrid dual-layer ﬁlm was prepared on diamond-like carbon (DLC) surface by depositing mobile lubricant multiply-alkylated cyclopentane (MAC) on 1H, 1H, 2H, 2H- perﬂuorodecyltrichlorosilane self-assembled monolayers (FDTS-SAMs). The formation of com- paratively uniformFDTS-SAMs onDLCsurfacewas veriﬁed by static contact anglemeasurement, X-ray photoelectron spectrometer, and atomic forcemicroscope (AFM). AFMresult showed that a high density of regular but discrete nano-scale island-like liquid droplets of MAC were dis- tributed on DLC surface with an interlayer of FDTS-SAMs to form hybrid AC–FDTS dual-layer ﬁlm.The average diameter and height ofMACdroplets onFDTS-SAMs are 30 nmand 35 Å, respec- tively, and the area covered by MAC droplets is ∼60 per cent. The tribological behaviour of the resulting hybrid ﬁlm was evaluated on a pin-on-plate test rig using Zdol-2000 ﬁlm and FDTS- SAMs as reference. The result showed that hybrid MAC–FDTS dual-layer ﬁlm exhibited the best reducing-friction capability, load-carrying capacity, and durability comparedwith Zdol-2000 and FDTS-SAMs at applied loads of 50–250mN. This may be attributed to the self-healing ability of themobileMAC lubricant to diffuse and cover the damaged or defective areas of the substrates.
