Title: Critical behavior of a microemulsion studied by small-angle neutron scattering
Author: Kotlarchyk, Michael; Chen, Sow-Hsin; Huang, John
Abstract: The critical behavior of a three-component water-in-oil microemulsion was studied by small-angle neutron scattering. Intensity spectra were analyzed by the treatment of critical scattering as arising from concentration fluctuations of polydisperse spheres. We propose a model capable of fitting the data over five decades of intensity variation. The critical exponents were determined to be ν=0.72+/-0.04 and γ=1.61+/-0.09. The average droplet size and width of the size distribution exhibited little temperature dependence (Refer to PDF file for exact formulas).
