Wettability of Amphoteric Surfaces : The Effect of pH and Ionic Strength on Surface Ionization and Wetting

We present a novel theory to predict the contact angle of water on amphoteric surfaces, as a function of pH and ionic strength. To validate our theory, experiments were performed on two commonly used amphoteric materials, alumina (Al2O3) and titania (TiO2). We find good agreement at all pH values, a...
