High internal phase water-in-oil emulsions and related microemulsions studied by small angle neutron scattering. 2. The distribution of surfactant
We have examined isotopically substituted concentrated emulsions and related microemulsions by small angle neutron scattering (SANS). The emulsions have 90% internal phase micron-scale water droplets in a continuous hexadecane microemulsion. The surfactants have polyisobutylene oligomer tails with acid-amide headgroups. Dilution experiments with surfactant concentration varying over a 75-fold range confirm that the oil phase component of the emulsion contains reverse spherical micelles. We have...[Show more]
