abstract = {Close to a planar surface, lamellar structures are imposed
upon otherwise bulk bicontinuous microemulsions. Thermally
induced membrane undulations are modified by the presence of
the rigid interface. While it has been shown that a pure
membrane's dynamics are accelerated close to the interface,
we observed nearly unchanged relaxation rates for membranes
spiked with large amphiphilic diblock copolymers. An
increase of the polymer concentration by a factor of 2–3
for the first and second surfactant membrane layers was
observed. We interpret the reduced relaxation times as the
result of an interplay between the bending rigidity and the
characteristic distance of the first surfactant membrane to
the rigid interface, which causes the hydrodynamic and
steric interface effects described in Seifert's theory. The
influence of these effects on decorated membranes yields a
reduction of the frequencies and an amplification of the
amplitudes of long-wavelength undulations, which are in
accordance to our experimental findings},
