Abstract

Laser structuring technique has been intensively studied because of its advantageous properties of non-polluting, low-cost and high materials utilization. Lasers can play a role of an alchemist on coloring metals with diverse colors, as reported. Both individual and iridescence colors can be obtained by lasers on metals surfaces. Laser induced periodic surface structures (LIPSS) are regarded as the main cause of the color. Furthermore, surfaces with different wetting properties can be achieved by lasers in metals or polymers. Roughness factor is the origin of the wetting behavior. However, the major disadvantage of the laser structuring is its low efficiency caused by direct-writing technique, in which a raster-scanning strategy is commonly applied. High-throughput production of functional surfaces is intensely desirable and remains as an ultimate challenge. In this work, we functionalize the metal surfaces with different colors by adopting femtosecond laser texturing technique, and the treated metals are subsequently used as the master molds for efficient production of hydrophobic surfaces of PDMS with an extremely strong adhesion force.
