High internal phase emulsion (HIPE) offers a superior template for a variety of applications. Despite a lot of advantages, it requires special strategies to form stable HIPEs, in particular, for particle covered HIPEs. In this presentation, we present an extremely versatile technique to produce a stable high internal phse Pickering emulsin (HIPPE) by controlling the interaction between a droplet and a particle. The attractive interaction between these two colloids facilitates adsorption of the particles onto the interface of droplets, and simultaneously suppresses desorption of particle from the interface. This enhanced adsorption and suppressed desorption allows a stable HIPPE to be formed with the minimal use of colloidal particles, but with no use of additional surfactant nor any surface modification of colloids. |
