Large-scale preparation of size-controlled Fe₃O₄@SiO₂ particles for electrophoretic display with non-iridescent structural colors.

ABSTRACT: Monodisperse colloidal particles have promising applications in electrophoretic displays with vivid colors, reversibility and low switching times. In this study, a facile, effective and large-scale strategy for preparing size-controlled Fe₃O₄@SiO₂ particles is reported. Multiple Fe₃O₄ particles were synthesized by a modified solvothermal method using sodium citrate as a surface modifier with a binary solvent, and were then coated with a SiO₂ layer to obtain a highly negatively charged surface via a modified Stöber method. Owing to the easily controlled sizes and sufficient surface charges, Fe₃O₄@SiO₂ particles can be assembled into colloidal amorphous arrays with the balance of electro
