Investigating the effect of morphology on hydrophobicity of ZnO nanostructures

In this work, a study on effect of morphology on hydrophobicity of ZnO nanostructures is presented. A case study was performed on the relationship between wetting states of aligned and unaligned ZnO nanowire arrays and the contact angle of a water droplet on a ZnO nanowires surface. Contact angle of 135° on surface with aligned ZnO nanorods and contact angle of 50-57° on surface with ZnO nanowires, is confirmed. This is in accordance to ZnO nanowires surface wettability to the Cassie-Baxter model. The surface wettability and hydrophobic nature of ZnO play a crucial role in biosensing, biomedical and microfluidic applications
