Abstract

Stability and rheological studies on gel emulsions (w/o high internal phase ratio emulsions, HIPRE) both with pure and commercial polyethyleneglycol alkyl ether surfactants are reported. Stability of gel emulsions at room temperature is increased by addition of NaCl to the internal phase; in contrast, no appreciable effect is found at higher temperatures. Rheological properties are influenced by both NaCl concentration and temperature. Apparent yield stress and elastic modulus are increased either by NaCl addition or temperature increase. Shear modulus as a function of volume fraction is analyzed in terms of droplet size and interfacial tension.
