Electrophoretic display (EPD) is a type of flexible display which has attracted wide attention. In this work, blue nanosized crystals of cobalt aluminum oxide (CoAlO) were precipitated on silica nanoparticles, and then the nanocomposites were coated with an ionic liquid polymer (PIL) to give blue electrophoretic particles. The blue nanocomposites (SCAs) formed possess an excellent spherical structure, and the average diameter is about 188 nm. The porous silica matrix presents a relative light density, and the blue CoAlO pigment offers excellent color. The outside ionic liquid polymer supplies the PIL/SCAs with a light density of 1.7915 g cm, excellent hydrophobicity and dispersion stability in the electrophoretic liquid. The fabricated single-particle EPD prototypes show a response time of 165 ms in the EPD cell with a 0.2 mm thickness, which is much faster than the commercial EPDs, and this is probably because of the unique composite structure.
电泳显示器（EPD）是一种备受广泛关注的柔性显示器。在本工作中，氧化钴铝（CoAlO）蓝色纳米晶体沉淀在二氧化硅纳米颗粒上，然后用离子液体聚合物（PIL）包覆这些纳米复合材料以得到蓝色电泳粒子。形成的蓝色纳米复合材料（SCAs）具有优异的球形结构，平均直径约为188 nm。多孔二氧化硅基质具有相对较轻的密度，而蓝色CoAlO颜料提供出色的颜色。外部的离子液体聚合物为PIL/SCAs提供了1.7915 g/cm的轻密度、优异的疏水性以及在电泳液中的分散稳定性。所制备的单粒子EPD原型在厚度为0.2 mm的EPD单元中显示出165 ms的响应时间，这比商用EPD快得多，这可能是由于其独特的复合结构。
