| Abstract Scope |
Two-dimensional (2D) nanofilms are promising candidates for lubrication and surface protection (eg. corrosion and wear resistance) for microelectromechanical (MEMS) and other small-scale components. They also can be used as boundary friction modifiers in formulated lubricants and greases, particularly in low-viscosity lubricants. Understanding how to not only control their friction properties, but how they would function over time as surfaces are exposed to ambient environments or the nanofilms are used in formulated lubricants. Using atomic force microscopy, we have measured the friction properties of these films under various environmental conditions, heat, and surface roughness and observed that interlayer adhesion compared with nanofilm-substrate adhesion can be controlled for the relevant application. Further, our environmental studies also point to conditions where certain characteristics or chemical functionality may be required for long-term stability of the nanofilms. |
