      abstract     = {We show for the first time the effect of telechelic
                      polymers asadditives in bicontinuous microemulsions. We
                      combined macroscopicobservations of the phase behavior with
                      microscopic measurements of thestructure by small-angle
                      neutron scattering (SANS) to recover the two elasticmoduli,
                      κ and κ̅, namely the bending rigidity and saddle-splay
                      modulus. Onthe basis of these results, we could classify the
                      effect of telechelic polymersalong with confinement,
                      expressed as the ratio of the polymer end-to-enddistance Ree
                      and the oil−water domain size d. Their unique property to
                      anchorat two points in the membrane (bridging) acts like a
                      switch from antiboosterto booster of the surfactant
                      efficiency (between low and ultralowconfinement). In the
                      region of medium confinement, all telechelic polymersare in
                      the bridging configuration and we have a maximum of the
                      boostingeffect, while at high confinement, the reversed
                      behavior is found whereanchoring and/or bridging do not play
                      any role anymore.},
