abstract = {The elastic constants of bicontinuous microemulsions,
consisting of water, oil (decane) and a surfactant. can be
modified by the addition of diblock-copolymers (boosting
effect). A similar decoration of the surfactant membrane is
possible in the lamellar phase. At high diblock copolymer
densities, in the brush regime, a change in the dependence
of the bending rigidity on the molecular size and
concentration of the diblock copolymer is predicted
theoretically. In particular a very strong dependence of the
bending rigidity on the radius of gyration of the diblock
copolymer (kappa proportional to R-5) is predicted. We have
studied the structure and dynamics of lamellar
microemulsions by small angle neutron scattering (SANS) and
neutron spin echo spectroscopy (NSE) in the brush regime,
with high diblock copolymer density. Decyl polyglycol ether
(C10E4) has been used as surfactant, the amphiphilic
diblock-copolymers were
polyethylenepropylene/polyethyleneoxide (PEP5-PEO5). The
influence of the diblock copolymer concentration when
entering the brush regime on the bending rigidity K and the
correlation length xi will be discussed.},
