Abstract:

This work proposes a novel, cost-effective, and simplified method to fabricate(reduced graphene oxide (rGO) nanorods. It is demonstrated that when a composite film made of polyvinylidene fluoride (PVDF) and the fabricated rGO is formed on a silver substrate, a unique structural morphology appears. This structure is unlike the general morphological structures of PVDF and rGO. The fabricated rGO has a nanorod-shapes of 0.54 nm to 1.15 \mum length and diameter in the 51- 64 nm range. The presence of \alpha and \beta phase PVDF and rGO in the composite has been confirmed using both X-ray diffractometer and Raman spectroscopy. Impedance characterization of the fabricated device shows constant phase characteristics in the frequency range of 126 kHz to 2 MHz with a constant phase angle at -63^{\circ } to -78^{\circ }. This indicates that the proposed rGO Nanorod-PVDF composite is suitable for the fabrication of a thin film fractor (fractional order device) with fractional order \eta = 0.70 to 0.88 and fractance value 0.08 to 3.08 nFs^{\eta }.
