Abstract
Recently, the hydrophobic surface has been attracted because of the excellent opto-physical properties. Various processing methods such as chemical, mechanical, photolithographic and laser processing are competitively introduced for fabrication of hydrophobic surface of polymer, metal and ceramics. In this paper, we fabricated the hydrophobic surface of copper metal by simple method which irradiated 355 nm UV-pulsed laser in order to shape microgrooves and increased surface roughness through oxidation process at room temperature. Finally the contact angle is dramatically increased by maximum $45^{\circ}$, as a result of oxidation which simply created nanostructures on the microstructures without expensive chemical process.
