Nano-patterns made of poly(methyl methacrylate) (PMMA) were fabricated on silicon wafer using a capillarity-directed soft lithographic technique. Patterns with three different aspect ratios were investigated for their adhesion and friction properties at nano-scale and for friction at micro-scale. The patterned samples exhibited superior tribological properties, at both these scales when compared to those of flat PMMA thin films.
