Hydrophobic Glasses Surfaces Modified With Iron Oxide

The present research is related to the Surface Science, mainly concerned with hydrophobic and superhydrophobic surfaces. The purpose of this work is basically to obtain a modified glass surface with high contact angle what is commonly found in materials with these properties. The first scientific demonstration of an artificial superhydrophobic surface was in 1990 decade1, when scientists could reproduce a characteristic found in some plants: their leaves showed specific roughness and hydrophobicity, so that, the droplets acquired a spherical shape when touched the leaves surfaces. Nowadays, this characteristic is called “The Lottus Effect”2. Intending to increase the glass hydrophobicity by increasing the contact angle between glass and water, iron oxide nanoparticles were incrusted on glass to obtain a texturized surface and reactive chemical sites that allowed also chemical modifications.
