Phase behavior of mixtures of side chain LC polyoxetanes with E7 and their field response |
| 초록 |
We prepared and characterized a series of side chain liquid crystalline LC homo- and co-polyoxetanes containing varying fraction of the mesogenic 4-decyloxy-4'-cyano-2’-fluorobiphenyl pendent and the nonmesogenic propoxy group. Miscibility of home- and copolyoxetanes (Co-LCPs) with E7 also was studied. The LC properties of the F-Co-LCPs / E7 mixtures were unique in that, although E7 is a nematic mixture, all the F-Co-LCPs / E7 mixtures form the layered smectic mesophases. A flexible plastic display was constructed utilizing this mixture and its display characteristics were evaluated. For a device of 10 μm thick active layer the threshold voltage was about 30 V and exhibited a rising response time of 150 ms. The most remarkable observation made was that the blends revealed excellent memory behavior. |
