摘要：
The different concentration of ZnNiFe2O4 nanoparticles dispersed Poly(m-phenylenediamine) (PmPD)/ZnNiFe2O4 nanocomposites were synthesized by in -situ chemical oxidative polymerization method and using auto combustion method for preparation of ZnNiFe2O4 nanoparticles. The synthesized PmPD/ZnNiFe2O4 nanocomposites were characterized by XRD, FTIR, SEM, TEM, TGA and VSM. The formation and crystalline size of PmPD/ZnNiFe2O4 nanocomposites were confirmed through XRD and FTIR. The surface, morphology and shape of the PmPD/ZnNiFe2O4 nanocomposites were studied by SEM and TEM. The concentration of ZnNiFe2O4 influenced the thermal stability of PmPD/ZnNiFe2O4 nanocomposites. The hysteresis loop of ZnNiFe2O4 and PmPD/ZnNiFe2O4 nanocomposites confirmed their ferromagnetic behaviour. The dielectric constant of samples was analysed with different temperatures and frequencies.
