Adsorption-induced deformation is a change in geometrical dimensions of an adsorbent
material caused by gas or liquid adsorption on its surface. This phenomenon is universal and
sensitive to adsorbent properties, which makes its prediction a challenging task. However, the
pure academic interest is complemented by its importance in a number of engineering
applications with porous materials characterization among them. Similar to classical
adsorption-based characterization methods, the deformation-based ones rely on the quality of
the underlying theoretical framework. This fact stimulates the recent development of
qualitative and quantitative models toward the more detailed description of a solid material,
e.g. account of non-convex and corrugated pores, calculations of adsorption stress in realistic
three-dimension solid structures, the extension of the existing models to new geometries, etc.
The present review focuses on the theoretical description of adsorption-induced deformation
in micro and mesoporous materials. We are aiming to cover recent theoretical works
describing the deformation of both ordered and disordered porous bodies.
