• Friction
• Wear
• Micro-structure

A novel micro-structured PDMS coating with high durability and relatively low friction was successfully replicated from a lotus leaf. Unlike the bio-inspired coatings developed previously, the micro-structured PDMS specimen could be fabricated in the form of a coating which could be successfully deposited on a solid surface. Results showed that friction and wear of the micro-structured PDMS specimens were significantly lower than those of the smooth specimens. It was also found that the wear resistance of micro-structured PDMS coating with 200 mu m thickness was much higher than that of the micro-structured PDMS bulk specimen. The drastically high durability of the PDMS coating specimen was attributed to frictional energy dissipation through elastic deformation of the micro-structures.
