| 英文摘要 | A double-layer lubricant film consisting of a multiply-alkylated cyclopentane (mac) mobile lubricant on octadecyltrichlorosilane self-assembled monolayer (ots-sam) was prepared. atomic force microscopy (afm) was used to examine the film surface. mac with thickness of 25 a was successfully coated on the ots-sam surface. mac was discretely distributed on the ots-sam surface, and the film contained evenly distributed islands with a typical diameter of 25 nm and an average height of 25 a. the area covered by the mac was approximately 70%. measurements were also performed on 50 angstrom zdol-2000 film and 25 angstrom ots-sam for comparisons. the film thickness was measured by gaerter elipsometer and the static contact anale was measured using a kyowa contact-angle meter. the thickness of the lubricant film determined by the afm was consistent with that measured by ellipsometer. the measured static angle of the 50 angstrom mac-ots double-layer film was about 110 degrees, slightly greater than that of 108 degrees of 25 angstrom ots-sam and that of 106 degrees of 50 angstrom zdol-2000. tribological properties of the three kinds of films were evaluated using a ball-on-plate type universal df-pm unidirectional sliding tribometer. the wom surfaces of the films were examined using a high precision non-contact surface profiler. all the films exhibited similar friction coefficients of about 0. 1 at a normal load of 0.5 n, but the mac-ots double-layer film exhibited extended durability and higher load-carrying ability compared with 50 angstrom zdol-2000 film or 25 angstrom ots-sam.
