Liquid Crystal Alignment Behavior on Transparent Cellulose Films |
| 초록 |
The liquid crystal (LC) alignment properties of LC cells fabricated with plant-based cellulose films were investigated. These carefully prepared polymer films exhibited good optical transparency in the visible light region (400-700 nm). For example, transmittance value (91 %) of the cellulose film onto glass substrate at 550 nm is better that (89 %) of the polyimide film, the most commonly used LC alignment layers. The LC cells made from the rubbed cellulose films showed the homogeneous planar LC alignment with parallel direction with respect to the rubbing direction. The electro-optical characteristics of the LC cells fabricated with the cellulose films such as applying voltage and response time were as good as those fabricated from rubbed polyimide films. We also found that the thermal stability of the LC cell made from the cellulose film is better than that of the polyimide film. |
