利用分子自组装技术制备了全氟辛酰胺丙基硅烷单分子膜,用X射线光电子能谱(XPS)对组装膜的表面元素进行了表征;接触角测试表明,该组装膜具有很好的疏水-疏油性,其对水的接触角高达105°,对正十六烷的接触角为50°.摩擦磨损实验结果表明,全氟辛酰胺丙基硅烷自组装单分子膜可以大大降低基片的摩擦系数,使载玻片的摩擦系数从0.85左右降低到0.14左右,而且低负荷下具有很好的耐磨性. The perfluorooctamido propylsilane monolayer was prepared by molecular self-assembly technique. The surface elements of the assembled films were characterized by X-ray photoelectron spectroscopy (XPS). The contact angle measurements showed that the assembled films had good hydrophobicity - oleophobicity with a water contact angle of up to 105 ° and a n-hexadecane contact angle of 50 ° Friction and wear test results show that perfluorooctamide propyl silane self-assembled monolayers can greatly reduce the substrate Friction coefficient, the slide coefficient of friction decreased from about 0.85 to about 0.14, but also has good wear resistance under low load.
