Abstract

The sodium perfluorooctanoate(SPFO)-dodecyltrimethylammonium bromide(DTAB) mixed micelles and the mixed micellar microenvironments (microviscosity and micropolarity) were studied by using NMR, ESR and surface tension. The results showed that SPFO and DTAB were capable of forming a mixed micelle in aqueous solution and the fluorocarbon chain of SPFO had strong interaction with the hydrocarbon chain of DTAB. The surface activity of SPFO-DTAB is much higher than SPFO or DTAB itself. The ESR spectra revealed a low polarity and a high viscosity in SPFO-DTAB mixed micellar core, indicating that a number of SPFO fluorocarbon chain had penetrated into the interior of DTAB micelles.
