Surface‐inactive, highly hydrophilic particles are utilized to effectively and reversibly stabilize oil‐in‐water emulsions. This is a result of attractive van der Waals forces between particles and oil droplets in water, which are sufficient to trap the particles in close proximity to oil–water interfaces when repulsive forces between particles and oil droplets are suppressed. The emulsifying efficiency of the highly hydrophilic particles is determined by van der Waals attraction between particle monolayer shells and oil droplets enclosed therein and is inversely proportional to the particle size, while their stabilizing efficiency is determined by van der Waals attraction between single particles and oil droplets, which is proportional to the particle size. This differentiation in mechanism between emulsification and stabilization will significantly advance our knowledge of emulsions, thus enabling better control and design of emulsion‐based technologies in practice.

范德华乳液：通过范德华吸引力由表面惰性亲水颗粒稳定的乳液

表面惰性，高亲水性的颗粒可用于有效和可逆地稳定水包油型乳液。这是水中颗粒和油滴之间的吸引力范德华力的结果，当抑制颗粒和油滴之间的排斥力时，范德华力足以将颗粒捕集在紧邻油水界面的位置。高亲水性颗粒的乳化效率取决于颗粒单层壳与包裹在其中的油滴之间的范德华力，并且与颗粒尺寸成反比，而稳定化的效率取决于单颗粒与油滴之间的范德华力。 ，它与粒径成正比。
