The first part of this book looks at the consequence of chemical
and topological defects existing on real surfaces, which explain
the wettability of super hydrophilc and super hydrophobic surfaces.
There follows an in-depth analysis of the acido-basicity of
surfaces with, as an illustration, different wettability
experiments on real materials. The next chapter deals with various
techniques enabling the measurement of acido basicity of the
surfaces including IR and XPS technics. The last part of the book
presents an electrochemical point of view which explains the
surface charges of the oxide at contact with water or other
electrolyte solutions in the frame of Bronsted acido-basicity
concept. Various consequences are deduced from such analyses
illustrated by original measurement of the point of zero charge or
by understanding the basic principles of the electrowetting
experiments.
