The interaction of solid particles with fluid interfaces in colloidal multiphase systems can lead to a wide range of fascinating and sometimes useful phenomena. Most of the research in this area has focused on ternary systems with two immiscible fluids and one particle species. After a brief review of some common characteristics, this article discusses recent insights and future opportunities regarding systems that confront particles with multiple types of fluid interfaces. focusing in particular on the interaction of particles with oil-coated bubbles in an aqueous media. Relevant examples include the particle-assisted reconfiguration of bubble-droplet morphologies, the separation of hydrophilic particles from aqueous slurries by oily bubble flotation, and the formation of capillary foams, a promising new class of foam materials.

胶体多相系统中固体颗粒与流体界面的相互作用会导致多种引人入胜的，有时有用的现象。该领域的大多数研究都集中在具有两种不混溶流体和一种粒子种类的三元体系上。在简要回顾了一些共同特征之后，本文讨论了有关面对具有多种流体界面类型的粒子的系统的最新见解和未来机会。特别关注颗粒与油中气泡的相互作用一个水性介质。相关示例包括气泡-液滴形态的颗粒辅助重构，通过油性气泡浮选将亲水性颗粒与水性浆料分离，形成毛细管泡沫（一种很有希望的新型泡沫材料）。
