高疏水性纳米彩色颗粒的制备及在电润湿显示中的应用

Review of Preparation of Highly Hydrophobic Nanoparticles and Its Application in Electrowetting Display

采用具有高疏水性的纳米彩色颗粒作为显示材料的潜力也越来越突出,通过以有机或无机粒子为染色载体,对有机或无机粒子进行表面功能化疏水改性,实现高稳定疏水的电润湿油墨,相较于传统的可溶性有机染料,其具有极高的耐光稳定性和颜色可调性,是电润湿显示技术产业化过程中不可忽视的一个技术方向。本文简要综述了高疏水性纳米彩色颗粒的制备工艺、表征方法,讨论了高疏水纳米颗粒用作电润湿显示油墨材料所面临的问题,分析了相应的改进措施。

With the deepening research on electro-wetting display technology(EFD),highly hydrophobic colored nanoparticles have great potential to be used as EFD colored oil materials.By using organic or inorganic particles as a dyeing carrier,surface-functionalized hydrophobic modification of organic or inorganic particles can be achieved through physical or chemical methods to achieve a highly stable hydrophobic electrowetting ink.Compared to traditional oil soluble organic dyes,highly hydrophobic colored nanoparticles have great advantages on light stability and color controllible.Thus,it is a very important technical direction on the way of EFD industrialization.We gave a brief review on the preparation and characterization of the highly hydrophobic colored nanoparticales in this paper,and we summarized the challenge of using this new material in EFD,discussed the possible solutions in the future.
