Abstract
Micellization of a cationic fluorocarbon surfactant with surfactants having various head groups in aqueous solution is discussed. The cationic fluorocarbon surfactant micelles can be characterized by growth from sphere to rod-like form, which is explained by counterion binding and packing ratio. Non-ideality of the mixed surfactant systems using interaction parameters obtained from a regular solution theory is greater for the cationic—cationic than for the cationic—non-ionic systems. The cationic—anionic systems show a larger negative interaction parameter and in particular, in the cationic fluorocarbon—anionic hydrocarbon mixed system, vesicles are formed.
