Effect of Graded Dispersion of SiC Particles on Dielectric Behavior of SiC/Epoxy Composite

Dielectric study of CoFe2O4/MWCNT/epoxy nanocomposites: Effect of temperature, concentration and irradiation

“…[35,40] At high frequency regime, the orientation of dipole stopped and electric diploes are unable to follows the rapid alteration of external applied field. [35,[41][42][43] The decrease in dielectric constant is in consistent with Koop's theory and Maxwell Wagner theory. [39,44] According to the theory, when ferrites are placed in external applied field the hopping of electrons and holes between Fe 2+ to Fe 3+ ions as result the mobile electrons drift towards the grain boundary and get accumulated in the well due to high resistance at grain boundary consequently, this process results in interfacial polarization.…”
