Bistability annealing process

The change in alignment layer crystallinity by the annealing process was evaluated by SEM and FTIR spectroscopy, and the bistability was evaluated by the response of the memory state to small disturbing electric fields. Three kinds of layers, S, A and C, were produced. The layer S was produced by the usual process, that is, a methanol/7re-cresol solution of nylon 6,6 was dried at 160 °C for 1.5 h in a...
