Alignment of lamellar block copolymer microstructure in an electric field. 1. Alignment kinetics

The kinetics of alignment of block copolymer microstructure in an electric field has been studied. The rate of alignment obeys a simple time-temperature-field superposition law when thermal history is well-controlled. Thermal history also strongly affects the alignment rate. It is proposed that observed trends can be understood in terms of mechanisms of defect movement and pinning
