Effects of Grooved Surface with Nano-Ridges on Amplification of Hydrophobic Property

Abstract:

This paper shows how much the size of groove and ridge, which were fabricated on the silicon wafer, affected on the hydrophobicity of the grooved surface without chemical treatments and with chemical treatment such as self-assembled monolayers (SAMs) of organic silane. Furthermore, the contact angles (CAs) of water droplet on specimens were measured and compared with theoretical CAs of droplet in Cassie-Baxter state. The experimental results indicated that the specimen with the extensive groove width had super-hydrophobicity as compared to the specimen with relatively narrow groove width. The highest CAs of chemically non-treated specimens and chemically treated specimens were 171.9˚ and 173.1˚. This work explains that the grooved surface with nano-ridges and SAM coating contributes to improve hydrophobicity of surface.
