Les émulsions stabilisées par des particules colloïdales, aussi appelées émulsions de Pickering, présentent une très grande diversité résultant de la grande variété de particules actuellement disponibles. Des particules d'origine naturelle ou synthétique, des particules sphériques rigides, de formes irrégulières ou très déformables peuvent toutes stabiliser des émulsions. Nous proposons dans cet article d'illustrer cette diversité, mais aussi de mettre en exergue leurs propriétés communes. Nous identifions les questions, qui, à notre avis, restent encore sans réponse et qui mériteraient que la communauté consacre des efforts supplémentaires dans un proche futur. Nous donnons des exemples de matériaux originaux élaborés à partir d'émulsions de Pickering.
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.
