The dynamics in dodecane/C10E5/water microemulsions determined by time resolved scattering techniques

Recently, an alternative approach to the determination of the bending elast ic constants of the surfactant film in droplet microemulsions was developed , which is based on a combination of neutron spin-echo spectroscopy (NSE) a nd dynamic light scattering (DLS). In this work the approach will be applie d to investigate another C10E5-based microemulsion containing the oil n-dod ecane. The determined values for kappa and <(kappa)over bar> compare well t o values determined for the n-octane containing system. Small-angle neutron scattering (SANS) data will also be presented and discussed. (C) 1999 Else vier Science B.V. All rights reserved.
