| dc.description.abstract | In this work, small angle neutrons scattering (SANS) was exploited to investigate the inner structure of a mixed system containing a nonionic fluorosurfactant (undecafluoro-n-pentyl-decaoxyethylene ether (C5F11(EO)10; FSO100) and 66% of a cationic surfactant dodecyltrimethyl ammonium bromide (DTAB) on a wide range of spatial resolution, at 25 °C . The data analysis of the corrected and normalized scattered intensities was based on the coexistence of two micellar populations, namely, homogeneous polydisperse spheres and stacked core–shell disc-like micelles. This fitting model was used assuming either a mixed micellization or a F/H segregation phenomena. The obtained results support to some degree the micellar mixing but do not exclude completely the occurrence of an intra- or extra-micellar segregation. A predictive stacking parameter calculated for the mixed system indicates a morphologic transformation with regards to the pure surfactants. | ar |
