Inversion of Particle‐Stabilized Emulsions to Form High‐Internal‐Phase Emulsions

Two triggers: Phase inversion of a particle-stabilized oil–water system from an ordinary oil-in-water emulsion (see picture, left; green: oil, pink: water) to a water-in-oil high-internal-phase emulsion (right) at a fixed oil/water ratio (27:73 vol %) can be simply driven by either a change of pH value or salt concentration in a single system. Scale bars: 30 μm. Detailed facts of importance to specialist readers are published as "Supporting Information". Such documents are peer-reviewed, but not copy-edited or typeset.
