A silica coating on hydrophobic BaTiO 3 nanoparticles is created using a reverse microemulsion route . The process is sufficiently controllable to target a tunable silica shell thickness by choosing appropriate BaTiO 3 concentrations. Increasing the concentration of BaTiO 3 nanoparticles is found to be an effective approach to decrease silica thickness.
