Recent Study of AC Electrical Behavior of Iron Nanoparticle Decorated Polymer Composite

This study was based on current efforts and breakthroughs in customising nano-scale structures of nanostructured conducting polymer materials to improve electrical characteristics, as given in the reviews. The goal of this research is to investigate the a.c electrical response of a PANI/FeNP/Graphene composite made in-situ with adhathodavasica plant extract in an ice-cold bath. Techniques such as FT-IR and SEM were used to characterise the samples. The AC conductivity measurements were performed in the frequency range 5x101–5x106 Hz at 298K with an HIOKI 3532-50 LCR Hi-tester. The layered structure of graphene nanosheets in the composite is depicted in SEM photographs. The homogeneous distribution of iron nanoparticles throughout the PANI matrix, as well as imine stretching frequency, are attributes of IR spectral data. The investigation of a.c conductivity provides evidence for the composites' transport properties. With a stepwise increase in graphene content in the PANI/FeNP/Graphene composites, AC conductivity values increase.
