中文摘要：

分别在羟基化硅片表面制备了多烷基环戊烷单组分润滑膜（MACs）、（3-胺丙基）三乙氧基硅烷自组装膜（APS—SAMs）和多烷基环戊烷／（3-胺丙基）三乙氧基硅烷双层润滑膜（MACs—APS），对比研究了不同润滑防护涂层的摩擦磨损性能．结果表明：在载荷0．1N、频率1Hz下，与APS—SAMs和MACs单组分膜相比，MACs—APS双层膜在保持较低摩擦系数的基础上，其耐磨性能显著提高，在失效前未发生明显磨损．在所制备的这种双层润滑薄膜体系中，流动性较好的MACs分子镶嵌在固定相APS—SAMs的网络中，因而产生较好的复合摩擦学性能．

英文摘要：

Multiply- alkylated cyclopentanes film, （3 -Aminopropyl）triethoxylsilane sell＂- assembled monolayers and a double - layer lubricant film consisting of a multiply - alkylated cyclopentane mobile lubricant on （3 - Aminopropyl ） triethoxylsilane self - assembled monolayers （ SAMs ） were prepared. Contact angle, thickness, surface topography and friction properties of these films were investigated. The results indicated that the multiply - alkylated cyclopentane/（ 3 - Aminopropyl） triethoxylsilane double -layer film exhibited low friction coefficient and extended durability ability compared with multiply -alkylated cyclopentane film and （3 -Aminopropyl）triethoxylsilane SAMs at a normal load of 0. 1 N and a sliding frequency of 1 Hz. And there was on obvious wear scar on the surface before the failure of the double - layer film. It is highly suggested that the mobile hydrocarbon MACs in the double - layer lubricant film was trapped and maintained among the APS - SAMs network and yield the best combination of tribological properties.
