Outline of Final Research Achievements |
Magnetically oriented samples of spontaneous form highly ordered molecular aggregation structure of liquid crystalline polymers were prepared. Using the aromatic polyesters having alkyl side chains, the layered or honeycombed structure formed in a superconducting magnet. It was confirmed that the aromatic main chains of these polyesters are oriented parallel to the magnetic field direction. The gas diffusion properties of honeycombed structure was significantly higher than those of layered structure. In addition, gaseous diffusion direction is 90° variation sample was found. These results were, to prove that the creation of new high-performance gas separation membrane with high permeability and separation.
