Stabilized Sunset Yellow FCF Coatable Polarizer by Photo-Polymerization |
| 초록 |
Sunset Yellow FCF (H-SY), a lyotropic chromonic liquid crystal (LCLC), was self-assembled to the oriented anisotropic film and its optical behaviors were investigated by the combined techniques of microscopy and spectroscopy. Furthermore, in order to stabilize the oriented H-SY films and to minimize the possible defects generated during and after the coating, photo-polymerization of acrylic acid (AA) added to the H-SY/H2O solution were carried out. Morphological investigation by bright-field transmission electron microscopy (TEM) clearly indicated that macroscopic cracks generated in the oriented H-SY films can be avoided by the photo-polymerization of AA. Furthermore, utilizing polarized UV-Vis spectroscopy, the degree-of-polarization (DOP) of the oriented H-SY films with and without the photo-polymerization was evaluated to be 92% and 80%, respectively. |
