摘要: Conducting polymeric nanocomposite containing Li–Ni–Sm–Fe–O spinel was synthesized by the chemical oxidizing of aniline in presence LiNi0.5Sm0.08Fe1.92O4 particles. The dielectric and electric modulus properties as-prepared samples were investigated over a frequency range from 106 to 109 Hz. constant (e′), loss (e″) dissipation factor (tan δ) for all presented relatively high values at low found decrease with frequency. e′, e″ tan δ lower than that pristine PANI. Electric analysis had been carried out understand electrical relaxation process. time became longer due introduction particles lowering crystallinity
