Abstract

The microscopic mechanisms of electric field induced alignment of block copolymer microdomains was discussed. Grain boundary migration and rotation of grains were two distinct processes revealed using time-resolved synchrotron small-angle x-ray scattering. Two distinct microscopic mechanisms dominated the reorientation process in a certain regime of polymer concentration and temperature. The integrated scattering intensity was found to drop during the initial stage of the reorientation process and increased at later times.
