Colloidal particles as liquid dispersion stabilizer: Pickering emulsions and materials thereof

Solid stabilized emulsions, also referred to as Pickering emulsions, are very diverse owing to the large variety of available colloidal particles from naturally occurring to synthesized ones, from hard to very deformable ones and from spheres to more complex shaped particles. Here we illustrate this variety and, despite this huge diversity, we aim at highlighting the common features. We discuss next the remaining open questions that, in our point of view, should sustain special efforts in the future and we illustrate elaboration of original materials based on Pickering emulsions.
