| 摘 要： | 基于PET塑料薄膜取代硬质玻璃作为基板材料制备柔性液晶盒时,采用传统制备工艺会产生盒厚度不均以及盒中残留气泡等现象,导致柔性液晶器件性能变差。采用辊压工艺可以有效地解决上述问题,文章对其工艺流程进行了详细描述。实验发现,通过在辊压工艺中加热两片基板以降低溶液的黏度,能够有效地避免气泡残留,获得厚度均匀的柔性液晶盒。应用辊压工艺和聚合物分散胆甾相液晶,成功地制备了尺寸为7cm2的反射式柔性双稳态液晶盒。利用正交偏光显微镜观察了聚合物分散液晶的相形态,紫外分光光度计测试了其光电性能:最高反射率为22.8%,对比度为2.259,阈值电压为78V,饱和电压为99V。 |

| Abstract: | As substrate materials rigid glass is commonly replaced by PET plastic films for preparing flexible LC cells,the traditional process may cause nonuniform thickness and trap air bubbles in LC cells which deteriorate property of flexible LC device.These problems can be effectively solved by a rolling technique.The detail process has been described in this paper.It was found that the viscosity of solution was reduced by heating the two substrates which avoids the interfusion of air bubbles in the solution and ... |
