Effects of Ni particles with different morphologies on electro-optical properties of nematic liquid crystal

  • 摘要: 将不同形貌的Ni颗粒(类碗状Ni颗粒、Ni花颗粒和Ni球颗粒)掺杂在液晶中制备了扭曲向列相(TN)液晶显示模式液晶盒,采用液晶综合参数测试仪对掺杂不同形貌Ni颗粒的向列相液晶(NLC)显示模式液晶盒的阈值电压、饱和电压、对比度及响应时间进行了研究。结果表明,掺杂Ni颗粒后,液晶的电光性能得到明显改善,阈值电压、饱和电压均有所降低,对比度明显增大,响应时间下降。其中类碗状Ni颗粒改善效果最为明显,驱动电压降幅达到13.77%,对比度增大35.55%,响应时间降低至9.390 ms。Ni颗粒的形貌及比表面积对液晶的电光性能有很大影响。比表面积及曲率大的Ni颗粒对液晶电光性能的改善效果好。
