Shape fluctuations of microemulsion droplets: a neutron spin-echo study

Hellweg T, Gradzielski M, Farago B, Langevin D. Shape fluctuations of microemulsion droplets: a neutron spin-echo study. Colloids and Surfaces A Physicochemical and Engineering Aspects. 2001;183-185:159-169.An alternative approach to the determination of the bending elastic constants of the surfactant film in droplet microemulsions was presented recently, which accounts for the viscosity differences of the liquids forming the microemulsion. In this work the approach will be applied to investigate a C8E3 and C10E4 based microemulsion containing the oil n-decane. The determined values for kappa and )over bar> are compared to results from macroscopic measurements. (C) 2001 Elsevier Science B.V. All rights reserved
