The replication was carried out on poly(methyl methacrylate) (PMMA) film spin coated on silicon wafer using poly (dimethyl siloxane) (PDMS) molds. The function properties of the replicated surfaces were investigated at micro-scale in comparison with those of PMMA thin film and uncoated silicon wafer. The coefficients of friction of the replicated surfaces were almost five times lower than those of the PMMA thin film and four times lower than those of the uncoated silicon wafer. The superior micro-tribological properties of the replicated surfaces could be attributed to the reduced real area of contact projected by the surfaces. (C) 2006 Elsevier B.V. All rights reserved.
