Preparation of superhydrophobic Fe2O3 nanorod films with the tunable water adhesion

We describe a simple and inexpensive method to prepare α-Fe(2)O(3) nanorods films on glass slides fabricated via a simple hydrothermal procedure at 120 °C. Such films exhibit a hierarchical microtexture, and after the surface modification, they show extraordinary superhydrophobicity and the controllable water adhesion. Such superhydrophobic surfaces of the ferric oxides imply wide industrial applications.
