Abstract
/MgO double-filler composite. Dielectric and AC conductivity studies demonstrated a frequency behavior consistent with Maxwell-Wagner-Sillars interface polarization. Increasing the ablation time resulted in a decrease in the dielectric constant and conductivity, which was attributed to the small size and good dispersion of the nanoparticles and the restricted charge mobility due to the interface adhesion force.
