Abstract in another language

We investigate the influence of the electric field on the phase behavior of diblock copolymers in concentrated solutions using synchrotron small-angle X-ray scattering (synchrotron SAXS). When heating the solutions through the order-disorder transition temperature T_ODT, we find a significant decrease in T_ODT with increasing electric-field strength. In addition we found a temperature regime in which it is possible to switch between the disordered and ordered state at constant temperature upon application of a moderate electric field.
