Abstract :
Surface self-cleaning is observed in nature through plant´s leaf (lotus) or animal´s skin. This extraordinary behavior is related mainly to surface structure and its roughness. In this work, Wenzel model have been used to predict the hydrophobicity of ZnO thin film grown by Spray coating on glass. The measured water drops contact angles over ZnO surfaces were found within the theoretical predicted values.
