In this paper, we report on the replication of surface topography of natural leaves such as Lotus and Colocasia onto thin polymeric films using a capillarity-directed soft lithographic technique. PDMS molds were used to replicate the surfaces. The replication was carried out on poly(methyl methacrylate) (PMMA) film coated on silicon wafer. The patterns so obtained were investigated for their friction properties at micro-scale using a ball-on-flat type micro-tribo tester, under reciprocating motion. Soda lime balls (1 ㎜ diameter) were used as counterface sliders. Friction tests were conducted at a constant applied normal load of 3000 μN and speed of 1㎜/s. All experiments were conducted at ambient temperature (24±1℃) and relative humidity (45±5%). Results showed that the patterned samples exhibited superior tribological properties when compared to the silicon wafer and non-patterned sample (PMMA thin film). The reduced real area of contact projected by the surfaces was the main reason for their enhanced friction property.
