Field Variables and Critical Phenomena in Microemulsions

  • D. Roux
  • A. M. Bellocq


Some general features of field variables and critical phenomena in multicomponent systems are discussed. Critical behavior of surfactants in solution is specially examined, and results for a ternary system composed with pentanol, water, and sodium dodecyl sulfate (SDS) are presented. The study of the phase diagram leads us to evidence of a critical point and an associated field-like variable. The critical behavior is studied using the temperature (path I) and the field variable (path II) as variables. In both cases, an Ising-like behavior is found.
