👉 The Robinson fluid is a colloidal suspension of spherical particles, typically composed of silica or other inorganic materials, suspended in a liquid medium. Discovered by James Robinson in the 19th century, this fluid exhibits unique properties due to the balance between attractive and repulsive forces among the particles. These forces, primarily governed by van der Waals attraction and electrostatic repulsion, prevent the particles from aggregating, resulting in a stable suspension. The fluid's behavior is often described by the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory, which explains the interplay of these forces. Robinson fluid's stability is crucial in various industrial applications, including catalysis, coatings, and pharmaceuticals, where maintaining a dispersed state is essential for optimal performance.
