采用聚合相分离原理制备了一种电光性能优良的新型液晶高分子膜——PDLC膜.从应用角度出发,创新性地使用白光而非可见光区某一波长的光表征PDLC膜的性能参数,如对比度、工作电压、响应视角等,测试结果表明该膜工作电压为20V、响应视角150°以上、寿命达105数量级且性能稳定,同时比较了基片材质的影响,发现塑料ITO基片制备的PDLC膜对比度性能更优越,且容易制成大面积、可折叠的显示器件,有着更广泛的应用价值.该膜在传感器以及分析仪器元器件如新型光栅等方面已显示出其潜在的应用前景. A new type of liquid crystal polymer (PDLC) film with excellent electro-optical performance was prepared by the principle of polymerization phase separation.From the application point of view, the performance parameters of PDLC film were innovatively characterized using light of a wavelength other than visible light, such as The experimental results show that the working voltage of the film is 20V, the response angle is more than 150 °, the lifetime is about 105 orders of magnitude and the performance is stable. Meanwhile, the influence of the substrate material is compared, and the PDLC The film is superior in contrast ratio and easy to fabricate a large-area, foldable display device, which has a wider application value. The film has shown potential application prospect in the fields of sensors and analytical instrument components such as novel optical rasters.
