abstract = {Using neutron spin-echo (NSE) spectroscopy in combination
with dynamic light scattering (DLS), we performed an
extensive investigation of the bicontinuous phase in ternary
water-surfactant-oil microemulsions, with extension to
lamellar and droplet phases. The dynamical behavior of
surfactant monolayers of decyl-polyglycol-ether (C10E4)
molecules, or mixtures of surfactant with long, amphiphilic
block-copolymers of type poly-ethylene
propylene/polyethylene oxide (PEP-PEO) was studied, under
comparable conditions. The investigation techniques provide
access to different length scales relative to the
characteristic periodicity length of the microemulsion
structure. Information on the elastic bending modulus is
obtained from the local scale dynamics in view of existing
theoretical descriptions and is found to be in accordance
with small angle neutron scattering (SANS) studies. Evidence
for the modified elastic properties and additional
interaction of the amphiphilic layers due to the polymer is
more pronounced at a larger scale. Experiments on oriented
lamellar phases, and also droplet phases, with anchored
block-copolymers offer more insight into the effective
layer-layer interaction and efficiency boosting associated
with the polymers.},
