Abstract
The kinetics of alignment of block copolymer microstructure in an elec tric field has been studied. The rate of alignment obeys a simple time -temperature-field superposition law when thermal history is well-cont rolled. Thermal history also strongly affects the alignment rate. We p ropose that observed trends can be understood in terms of mechanisms o f defect movement and pinning.
