Fluid-bicontinuous emulsions stabilized by colloidal particles

摘要

Using controlled spinodal decomposition, we have created a fluid-bicontinuousstructure stabilized by colloidal particles. We present confocal microscopystudies of these structures and their variation with kinetic pathway. Ourstudies reveal a rigid multilayer of colloidal particles jammed at theinterface which prevents the liquids demixing for many hours. The arrangementof two-fluid domains, interpenetrating on the meso-scale, could be useful as amicroreaction medium.
