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 pure
membrane dynamics are accelerated close to the interface, we
observed nearly unchanged relaxation rates for membranes
spiked with large amphiphilic diblock copolymers with
respect to the bulk. 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.},
