Abstract: After a short introduction about neutron scattering, the audience is directed to examples involving surfactants. Results from microemulsions with polymeric additives are summarized with a deeper view on a tapered polymer. Then, microemulsions exposed to hydrophilic planar surfaces are in the focus. The method of grazing incidence neutron scattering provides excellent possibilities to study structure and dynamics at the solid-liquid interface. Dispersing clay particles in the microemulsion takes the view from model planar surfaces to macroscopically observable phenomena such as rheological properties. Finally, the example of liquid bilayers in aqueous environment reveals viscoelastic properties on the nanosecond time scales. The lecture is closed by looking on the future of grazing incidence neutron scattering experiments.
