| It has been shown that self assembled monolayers (SAMs) of alkylsilane or fluorosilane compounds with chain lengths of C10 – C18 reduce adhesion and friction on molecularly flat surfaces. The organization of SAMs on nanoasperities can be significantly affected by nearest neighbor interactions. In this work, silanes with various terminal groups including –CH3, -OH, -COOH, and NH2 groups are assembled on silica nanoasperities to probe how introducing hydrogen bonded interactions between chains will influence the nature of the film stability. The details of the self-assembly and the nature of the adhesion on both molecularly flat silica and curved silica nanoasperity surfaces will be described. |
