| Popis: |
A given substrate favors a certain orientation of mesophase molecules at the substrate-mesophase interface. This favored orientation extends from the surface into the bulk of the mesophase, thus producing a certain thickness of uniform orientation. We selected five cholesteryl esters from the homologous series of aliphatic esters of cholesterol and studied the thicknesses of the uniformly oriented mesophases produced in fine glass capillaries. The inside walls of the capillaries were either bare glass or coated with thin films of various chemicals. The results show a wide variety in the thickness of uniform orientation depending upon the mesophase textures and the treatment of substrate surface. |
