Abstract

The method of building micro-structures on the surface of certain materials could build a regular structure on the surface of the material to ensure the consistency of the material surface hydrophobic properties. In this paper, the all-optical method has been applied to produce two-dimensional surface relief grating on the surface of fluorine-containing azobenzene polymer film by using this method as an approach combined with the material’s properties of photoresponsive and low surface energy. The hydrophobic property of the final “two dimensional surface relief grating” has also been tested. Period combinations of 500nm×500nm, 500nm×600nm, 600nm×700nm, 700nm×800nm and the other eleven has been used to fabricate two-dimensional surface relief grating and their final results have been compared. The results show that, for the same period of grating, the contact angle becomes larger with the increase of the modulation depth. However, the contact angle becomes smaller as the grating period increases. Above all, the period and modulation depth of two-dimensional grating have a great impact on the hydrophobicity.
