Abstract
Solution properties or mixed fluorocarbon—hydrocarbon surfactant systems have been investigated with dynamic and static light scattering and with fluorescence-probe measurements.
The systems are mixtures of hexadecylpolyoxyethylene ether (C16POE20) with ammonium perfluorooctanoate (APFO) and/or with ammonium perfluorodecanoate (APFDe). When the concentration of fluorocarbon surfactant increases, the mutual diffusion coefficient and the second virial coefficient of mixed micelles increase, but the micelle molecular weight and the micropolarity decrease. The mutual diffusion coefficient and the second virial coefficient of mixed micelles in C16POE20/APFDe are larger than those in the C16POE20/APFO system, but the micelle molecular weight of C16POE20/APFDe is smaller than that of C16POE20/APFO.
It is found that C16POE20, a hydrocarbon non-ionic surfactant, mixes well with APFO and/or APFDe, a fluorocarbon anionic surfactant, and the mixed micelle is formed more easily with the surfactant containing a longer fluoroalkyl chain (APFDe) than with that having a shorter fluoroalkyl chain (APFO).
