Abstract
The present method comprises determination of surface polarity of an inorganic material by measurement of the net heat of inert gas adsorption on the material surface, preferably by measurement of the BET constant C. The analysis is fast and easy to execute, and provides high signal-to-noise ratio. It is applicable to many surfaces, such as those containing silanol groups, regardless of the nature of the hydrophobic groups used in surface treatment of the material.
