摘要： Methods of making robust bijels include dispersing metal oxide precursors and/or metal salts into at least one phase of a bijel and hydrolyzing and condensing the metal oxide precursors and/or metal salts in a sol-gel reaction to form sintered bridges between interfacially jammed surface-active nanoparticles. The methods can be used with any bijels, including those produced during solvent transfer-induced phase separation (STRIPS) methods and other methods. A robust bijel includes chemically sintered bridges between the interfacially jammed surface-active nanoparticles. Methods of making nanocatalyst-functionalized sintered bijels include adsorbing metal salts to a surface of sintered interfacially jammed nanoparticles of bijels, and reducing the metal precursors on the surface of the sintered nanoparticles. Nanocatalyst-functionalized sintered bijels include catalytically active metal or metal oxide nanocatalysts on a surface of the sintered interfacially jammed surface-active nanoparticles.

摘要： This disclosure demonstrates a new method to produce three dimensional multiphasic structures, including bijels, via vapor-induced phase separation (VIPS). In VIPS, the evaporation of the co-solvent from a ternary mixture of oil, water and ethanol, induces phase separation. Particles present in the mixture attach to the interface and arrest the phase separation between water and oil. VIPS enables, inter alia, the fabrication of films and coatings via spreading or spraying particle-laden suspension onto a surface without the need for an outer aqueous phase.
