摘要: The microemulsion model of de Gennes et al., which is a modified version the earlier Talmon and Prager, further by imposing microscopic cell‐size cutoff. Two free‐energy minima compete lead to composite surface consisting two intersecting sheets. phase arises from one sheet oil‐ water‐rich phases with it may be in equilibrium arise other. Schulman condition, according surfactant‐film pressure equals oil–water interfacial tension, found hold good approximation middle‐phase that contains comparable amounts oil water. water‐filled domains are about 75–80 A across. That such high osmotic compressibility would opalescent or turbid due fluctuations composition. shows range equilibria like seen experiment, including two‐ three‐phase equilibria, critical poin...
