Abstract
We report on micellization of nonionic fluorosurfactant Zonyl FSN-100 in aqueous solutions studiedby means of NMR spectroscopy, light and small-angle X-ray scattering, surface tension measurements,isothermal titration calorimetry and fluorescence spectroscopy. The results allow for determination ofbasic parameters of Zonyl FSN-100 association like critical micellar concentration, size and associationnumber of Zonyl FSN-100 micelles which have a core-shell structure with the core of fluorocarbon chainsand the shell of oligo(ethylene oxide) chains.
Time-resolved fluorescence spectroscopy studies using1,6-diphenyl-1,3,5-hexatriene (DPH) as a fluorescent probe indicate that DPH can be solubilized in themicelles despite the general assumption about the immiscibility of hydrocarbon compounds with thefluorocarbon core of the micelles.
