Abstract:
The structure of aqueous solutions of two polyoxyethylene non-ionic amphiphiles, C10E5 and C8E4, is studied by small-angle neutron-scattering along isothermal paths crossing the isotropic single-phase region from 0% to 100% amphiphile volume fractions. The scattered intensity I(k) shows a peak at a value km, which grows monotonically as the amphiphile volume fraction φ{symbol} increases. The interpretation of the scattering data lead to the following conclusion: as Φ increases the micellar structure becomes less and less sharp, but some orientational correlations between neighboring amphiphile molecules are preserved even in the pure amphiphile phase.
