采用自组装方法在羟基化硅基底表面制备硬脂酸/环氧硅烷双层膜,采用接触角测定仪、椭圆偏光仪、红外光谱仪、原子力显微镜、扫描电子显微镜和UMT-2MT型摩擦磨损试验机评价薄膜结构及其摩擦磨损特性.结果表明:自组装双层膜对水的接触角为96°,膜厚2.8 nm,双层膜中烷基链呈现较好有序性,在1 μm×1 μm扫描面积内表面均方根粗糙度(RMS)为0.227 nm.自组装硬脂酸/环氧硅烷双层膜能够有效降低基底的摩擦系数,摩擦系数稳定在0.12左右,同时表现出优异承载抗磨性能,在载荷0.5 N、1 N和2 N下,耐磨寿命分别为14 200 s以上、7 500 s和1 800 s |

A self-assembled dual layer film was successfully prepared on single-crystal silicon substrate by chemical adsorption of stearic acid (STA) molecules on self-assembled monolayer of (3-glycidoxypropyl) trimethoxysilane ( GPS) with terminal epoxy group. The structure and morphology of the dual-layer STA-GPS film were characterized by means of ellipsometric thickness measurement, contact-angle measurement, Fourier Transformation Infrared spectrometric analysis, and atomic force microscopic analysis. The dual layer film was hydrophobic with the contact angle for water to be 96° and the overall thickness about 2. 8 nm. The FT-IR spectra indicated that the film has local order structure. Atomic force microscopic image showed that the dual layer film was relatively smooth and homogeneous with RMS of 0. 23 nm. Tribological properties of the dual-layer STA-GPS film were also investigated on a^ UMT-2MT tribometer using ball-on-plate mode. The film greatly reduced friction coefficient and possessed better load-carrying capacity and antiwear ability, beacauce the interchain hydrogen bonds among the molecules en-chanced the stability of dual layer film against rubbing the counterpart ball and endowed it an excellent antiwear a-bility |
