Bicontinuous interfacially jammed emulsion gels (bijels) are a unique class of soft matter that is produced by arresting the spinodal decomposition of biphasic mixtures via the interfacial attachment and jamming of particles. This presentation will describe our efforts in manufacturing bijels from a homogeneous ternary mixture of water, oil, and co-solvent by triggering phase separation via the removal of the co-solvent. The use of silica nanoparticles and ionic surfactants enables the continuous and scalable manufacturing of bijels with a wide range of morphology, mechanical properties and domain sizes down to a few hundred nanometers. The effect of the solvent removal process (extraction vs. vaporization) on the microstructure of bijels will be described. In addition, I will also highlight potential applications of these bijels in reactive separation, membrane separation, and passive daytime radiative cooling.
