    Abstract

    High internal phase ratio emulsions (HIPREs) are a kind of emulsions characterized by a dispersed phase volume fraction higher than 0.74. In the last years much attention has been paid to their rheological properties and to their use for the preparation of low-density porous materials. However, in spite of their advantageous features concerning compartmentalization at different scale lengths with hydrophilic and hydrophobic domains and high internal phase ratio, little attention has been given to diffusion, an issue which can have a striking influence in many properties and applications of HIPREs. This review gives an overview on the work carried out in the last years concerning diffusion in highly concentrated emulsions from theoretical and practical points of view. © 2012 Elsevier Ltd.
