摘要: 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.

Abstract: Low surface free energy and ultrathin film of Perfluoroctanoxamidepropyltrimethoxyl Silane SAM was fabricated on microscope slide substrate by molecular self-assembled process.Contact angle measurement and XPS analysis show that the SAM has been prepared successfully with the property of water and oil repellency.The results of the friction and wear test show that this SAM can decrease the friction coefficient of the substrate significantly.
