Abstract

<p>The effects of shear flow on a polymeric bicontinuous microemulsion were investigated using neutron scattering, light scattering, optical microscopy and rheology. Low strain amplitude oscillatory shear measurements revealed behavior similar to block copolymer lamellar phases just above the order-disorder transition. It was found that with the increase in shear rate, the sample resembled an immiscible binary polymer blend with the block copolymer playing no significant role while the stress increased strongly with the shear rate.</p>
