The study of solid particles residing at fluid-fluid interfaces has become an established area in surface and colloid science recently, experiencing a renaissance since around 2000. Particles at interfaces arise in many industrial products and processes such as antifoam formulations, crude oil emulsions, aerated foodstuffs, and flotation. Although they act in many ways like traditional surfactant molecules, they offer distinct advantages also, and the area is now multidisciplinary, involving research in the fundamental science and potential applications. In this Feature Article, the flavor of some of this interest is given on the basis of recent work from our own group and includes the behavior of particles at oil-water, air-water, oil-oil, air-oil, and water-water interfaces. The materials capable of being prepared by assembling various kinds of particles at fluid interfaces include particle-stabilized emulsions, particle-stabilized aqueous and oil foams, dry liquids, liquid marbles, and powdered emulsions.
近年来，固-液界面处固体颗粒的研究已成为表面和胶体科学领域的一个成熟分支，自 2000 年左右以来经历了复兴。界面处的颗粒存在于许多工业产品和工艺中，如消泡剂配方、原油乳液、充气食品和浮选。虽然它们在很多方面都像传统的表面活性剂分子，但它们也有明显的优势，而且该领域现在是多学科的，涉及基础科学和潜在应用的研究。在这篇专题文章中，我们根据自己小组的最新工作，介绍了人们对此类研究的部分兴趣，包括油-水、气-水、油-油、气-油和水-水界面处颗粒的行为。通过在流体界面处组装各种颗粒，可以制备出颗粒稳定乳液、颗粒稳定水相和油相泡沫、干液体、液滴和粉末乳液等材料。
