Department of Chemistry, College of Science, University of Hafr Al Batin, PO Box 1803, Hafr Al Batin, 39524, Saudi Arabia 10.3762/bjnano.11.103 Abstract High permittivity and breakdownstrength are desired to improve the energy storage density of dielectric materials based on reinforced polymer composites
excellent dielectric properties with high permittivity (25.2) and low loss (0.04) at high frequency (106 Hz). A thick PTh encapsulation layer on the surface of the BTO nanoparticles improves their breakdownstrength from 47 to 144 kV/mm and the energy storage density from 0.32 to 2.48 J/cm3. A 7.75-fold
increase in the energy storage density of the BTO-PTh nanoparticles is attributed to simultaneously high permittivity and breakdownstrength, which are excellent for potential energy storage applications.
