介绍了一种原子力显微镜在润滑系统中的应用，如有机Langmuir-Blodgett薄膜。局部弹性顺应性测量同时与地形和摩擦的氟碳化合物和碳氢化合物的混合物的薄膜。在相分离的碳氟化合物区域上，发现了比碳氢化合物区域更高的摩擦和更低的杨氏模量。如果薄膜与具有更大横截面积的反相聚合物复合，则在更硬的碳氢化合物区域上观察到随机发生的粘着磨损。碳氢化合物膜剩余面积的定量分形分析提供了一个线性的粘附磨损依赖于扫描周期数。
An atomic force microscopy study is presented on lubricating systems, such as thin organic Langmuir–Blodgett films. Local elastic compliance was measured simultaneously with topography and friction on thin films of mixtures of fluorocarbons and hydrocarbons. On the phase‐separated fluorocarbon domains, higher friction and lower Young’s modulus than on the hydrocarbon domains was found. Adhesive wear has been observed to occur randomly on the stiffer hydrocarbon domains if the film is complexed with a counterion polymer of a larger cross‐sectional area. A quantitative fractal analysis of the hydrocarbon film remaining areas provided a linear adhesive wear dependence on the scan cycle number.
