Poly(1,6-heptadiyne)/NiFe2O4 composite as capacitor for miniaturized electronics

Impedance spectroscopy-based electrical measurements were conducted on different molecular weight (MW) Poly(1,6-heptadiyne)s (PHDs) embedded PHD/NiFe2O4 nanocomposites. Nanocomposites conductivity result demonstrated the conductivities of around(nanocomposite Root mean square (RMS) current is 12-15 times greater than DC current of PHDs at 27 degrees C). Additionally, dielectric loss and capacitance characteristics suggested the nanocomposite (4500 MW PHD) device quality factor is 35.7 at 1 kHz, which is similar to 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. [GRAPHICS]
