摘要：
Micellization of anionic and cationic fluorocarbon surfactants in mixtures of ethylene glycol/H2O and ethanol/H2O has been investigated by measuring surface tension and absorption spectra of a dye. The critical micelle concentration (CMC) values of both surfactants determined from the surface tension measurement decrease and then increase with an increase of ethylene glycol or ethanol concentration in the mixtures. In higher concentrations of ethanol, in which the CMC can not be determined from the surface tension measurement, the dye method is useful to estimate the CMC of both surfactants.
