摘要

We have investigated the microstmctures of the solid residue left behind after the evaporation of solid-stabilised emulsions. The correlation between the micro-structure and the properties and preparation conditions of the emulsions will be thoroughly discussed. The type of microstructure is related to the conditions (oil type, oil content, particle type, particle concentration and emulsion type) of the initial emulsion. Solid residues left after evaporation of oil-in-water emulsions containing volatile oils (relative to water) show a "knobbly" microstructure. When oils with similar or lower vapour pressure to that of water were used, "sponge-like" structures were obtained. For emulsions containing volatile oils, the mean drop diameter is similar to the mean pore diameter, whereas when oils with low vapour pressure are used, the pores are much smaller. Finally, this paper will illustrate that stable tolu-ene-in-water emulsions leave porous microstmctures, whereas water-in-toluene emulsions and emulsions close to the phase inversion show sheet-like or "knobbly" structure.
