2. Generating porosity with highly concentrated emulsions

2.1 Highly concentrated emulsions

An emulsion is considered highly concentrated when the volume of the internal phase (Φ) represents more than 74% of the total volume. This threshold corresponds to the maximum volume occupied by uniform spherical water droplets arranged in such a way that they do not undergo deformation. Above 74%, the drops deform to occupy as much space as possible. These concentrated emulsions are subsequently called HIPE (High Internal Phase Emulsion).

Lissant was one of the first authors to describe the structures and properties of HIPEs in a work that has become a classic in the field
