Abstract: Nanofabrication for Surface fictionalization have been attracting abundant research interests for the novel electronic, optical and mechanical properties of various nanostructures exhibiting broad potential applications in numerous fields, such as catalysis, clean energy and life sciences. The ordered micro/nano structure on the solid surface, which can endow materials with unique properties such as super-hydrophobic, super-adhesion, super-light-absorbency and so on, has comprehensive application foreground in the field of industry, aviation, aerospace and medicine. For this reason, the development of efficient and economic techniques for producing surface micro/nano structure is an important work. In a mass of physical, chemical and mechanical techniques for nanofabrication, the laser-assisted methods have shown to be efficient and environmentally friendly, which aroused many researchers’greatest attention. A wide range of laser sources, especially the ultra-short laser pulses owe to its minimal thermal and mechanical damages, have been used to fabricate spatially periodic structures on the surface of metals, semiconductors, dielectrics and polymers. Femtosecond (fs) laser direct inducing ordered surface structure has been demonstrated to be a promising method for producing of functional surface structures. In this talk, we will introduce our recent research progress in Surface functionalization.
