Abstract

In this study we investigated the morphology transition of microemulsion droplet induced by polymer confinement using a small angle neutron scattering (SANS) technique. By confining the polymer chain strongly the scattering profiles showed the following changes; 1) a characteristic scattering peak corresponding to the size of droplet shifts to the higher q side, and 2) the scattering intensity in the low q region increases considerably. These changes of the scattering profiles can be described by a rod (or sphero-cy finder) model. Thus, the strong confinement of polymer chains in droplets induces the morphological transition from spherical to rod-like droplet.
