Nanocomposites conductivity result demonstrated the conductivities of around (Formula presented.) (nanocomposite Root mean square (RMS) current is 12–15 times greater than DC current of PHDs at 27° C). Additionally, dielectric loss and capacitance characteristics suggested the nanocomposite (4500 MW PHD) device quality factor is 35.7 at 1 kHz, which is ~13.89 times superior than that of NiFe2O4 alone sample, also ‘Q’ value for highest MW PHD nanocomposite is 50% enhanced than NiFe2O4. Moreover, the capacitance result suggested the 12400 MW PHD nanocomposite nearly frequency-independent capacitance (15–20pF) over a frequency range of 500 Hz–500 kHz. © 2020 Taylor & Francis.Article
