Suspension Stability of BaTiO3 Nanoparticles under Electrical Applied Field
The suspension stability was investigated as the function of particle number concentration, applied force, and the distance between cathode and anode. The suspension was prepared by using BaTiO3 nanoparticles in a mixed solution with ethanol and acetylacetone. The highest zeta potential value was 30 mV, when the mixing ratio of EtOH and Acac was 75 : 25. EPD conditions of BaTiO3 nanoparticles suspension with 0.05 wt% were settled at the conditions of an applied dc field of 20 V/ and an electrode distance of 1.5 at 300 seconds of deposition time.
