Abstract

In this paper, silica nanoparticles and silica coated with ionic liquid polymer nanoparticles (PIL/SiO₂) were prepared. They are both monodisperse and smooth spheres, and also own suitable densities and excellent chromaticity. Porous silica benefits their low density, which decreases the gravitational sedimentation and avails electrophoretic mobility. The ionic liquid polymer coating of PIL/SiO₂ not only favors hydrophobicity and dispersity stability, but also helps the enrichment of trace polar impurities around the particles, which makes for ionization effect and electrophoretic mobility. The PIL/SiO₂ show greatly improved hydrophobicity and electrophoretic mobility. The PIL/SiO₂ in the fabricated EPD prototype with thickness of 0.2 mm shows response time of 155 ms, much faster than the silica nanoparticles, TiO₂ previously reported and commercial EPDs.
