Enhencement of Electro-optical Performance in Holographic Polymer Dispersed Liquid Crystal Based on Silicon Polymer |
| 초록 |
The electro-optical performance characteristics were investigated in holographic polymer dispersed liquid crystal (HPDLC) transmission gratings with the addition of silicon polymer. To minimize driving voltage in HPDLC various amounts of vinyloxy-trimethylsilane and vinyltrimethoxysilane have been added to the conventional polyurethane acrylate (PUA) system. It was founded that HPDLC based on polymer matrix containing silicon atom showed low driving voltage compared with conventional PUA system, which is subject to the decreased interface energy between polymer and LC. Such HPDLC also showed high diffraction efficiency due to the great phase separation. |
