摘要：
在这篇文章中，动态力显微镜研究的有机硅烷，接枝在二氧化硅支持的自组装单分子膜，报告。使用以官能团（乙二醇）或甲基封端的有机硅烷。研究了反应时间和溶剂组成对接枝的影响，以提高自组装膜的均匀性。数值模拟的方法，收回曲线，在攻丝模式下获得的，进行了比较实验。获得了接枝有机层的机械响应和高度等信息。
英文摘要：
In this article, a dynamical force microscopy study of self-assembled monolayers of organosilanes, grafted on a silica support, is reported. Organosilanes, terminated either with a functional group (ethylene glycol) or with a methyl group, were used. The influence of the reaction time and the solvent composition on the grafting was investigated to improve the homogeneity of the self-assembled monolayers. Numerical simulations of approach-retract curves, obtained in the tapping mode, were performed and compared to experimental ones. Informations, such as mechanical response and height of the grafted organic layers, have been obtained.
