It has been reported that various functions can be added to material surfaces by forming microscopic uneven structures. These functions include reduction of friction and wear of sliding parts, reduction of adhesion of small objects, improvement of compatibility of biomaterials, and changes in wettability [1-4]. Therefore, the control of wettability is one of the areas of active research on surface modification of materials. The formation of micro-periodic structures on the surface of materials by femtosecond laser irradiation has attracted much attention. Periodic structure called LIPSS (Laser Induced Periodical Surface Structure). However, an originally hydrophilic surface tends to be hydrophilic after modifying a material. In addition, hydrophobic surfaces with high water adhesion have attracted much interest. In this study, we attempted to form a micro periodic structure by femtosecond laser processing in order to give water repellency to iron surface that is originally hydrophilic.  The hydrophilic iron surface can be changed to a hydrophobic one. We demonstrate the high water adhesion after formation of LIPSS structures on Iron surface.
