These boundary regions are critical and very important to control because they influence the short- and long-term properties of clay–polymer-based multicomponent materials. It is thus imperative to assess the surface properties of clays and their polymer nanocomposites by surface-sensitive techniques. Toward this end, and from the authors' experience, much time and effort were spent on X-ray photoelectron spectroscopy and inverse gas chromatography for the determination of the surface chemical composition and thermodynamics within a depth of ∼10 nm. In addition, nitrogen adsorption served to determine the specific surface area and pore volume for pristine and modified clays as well as their polymer nanocomposites. Infrared spectroscopy in the attenuated total reflectance or diffuse reflectance infrared Fourier transform (DRIFT) mode probes the chemical bonds at the surface of the nanocomposites and changes are tracked efficiently. Particularly, DRIFT is specific to powder particle surfaces. By gathering these techniques (and less frequently employed ones) in one single chapter it is hoped to provide the expert and the newcomer with a combination of analytical tools to get a broad picture of surface physicochemical properties of clay–polymer nanocomposites.
