Abstract
Polymer/LC composite films of various compositions, potentially applicable for optical displays, have been prepared from poly(diisopropyl fumarate) (PDF) and E8 by solvent casting. Effects of film composition, applied electric voltage and frequency, and temperature on the electro-optic performance are reported. In addition, phase transition temperature and orientation changes in the composite have been studied using DSC and X-ray diffractometer, respectively. Threshold voltages of PDF/E8 composite films were around 25 VP p-p independent of composition. Rise time decreased with increasing LC content.

표시소자로서 응용이 가능할 것으로 짐작되는 고분자/액정 복합막을 다양한 조성에 걸쳐 용매증발법으로 제조하였으며, 막조성, 인가전압과 주파수 및 온도가 복합막의 전기광학적 특성에 미치는 영향을 체계적으로 연구하였다. 아울러 DSC 및 X-ray회절장치를 이용하여 복합막의 상전이 온도 및 director 배향을 조사하였다. 복합막의 문턱전압은 조성에 관계없이 25VP-P 부근이었으며, 액정함량이 증가할수록 rise time은 감소하였다.
