Preparation and Characteristics of Hydrophobic Wettability Function Micro-Nano Structures Surface Fabricated by Femtosecond Laser
Sayed Abdul Moqim Hussaini
Various micro/nanostructures can be prepared directly on the metal surface by using a femtosecond laser. These structures provide the metal surface with good wettability, for example, hydrophilic or hydrophobic function. Based on these functional characteristics, they find important applications in fields such as aerospace, architecture, medicine, and solar energy. In this paper, we use the femtosecond laser pulse on the stainless-steel surface and scan with a pitch smaller than the size of the focused beam size. After homogeneous laser irradiation on the surface, a columnar two-scale micro/nanocomposite structure have been prepared. The results of this paper show that the contact angle of the micro /nano-structured surface can reach up to 148.6o after silanization. This discovery is of significant importance for the selection of the base materials for the preparation of metal wettability surface by micro/nanostructures.
