Abstract
Mg ferrite nanoparticles have been synthesized using the citrate-nitrate auto-combustion technique. Also, polypyrrole (PPy) has been synthesized using a chemical polymerization technique. Physically blending ferrite with PPy and/or rGO in various ratios has produced composite samples. The XRD indicates that the ferrite nanoparticles are in a crystalline state with lattice constant 0.845 A and crystallite size 40 nm, and the composite samples contain PPy and rGO as intended. FTIR analyses indicate vibrational modes of octahedral at 405cm-1 and tetrahedral mode at 565 cm-1 of spinel structure. The EDX analysis of Fe, Mg, O, C, and N verified the chemical composition of pure ferrite and its composites. DC conductivity has been measured for all samples as a function of temperature. The ferrite/PPy composite samples exhibit greater DC conductivity compared to the pure ferrite sample and the ferrite/rGO sample. The composite of MgFe2O4/10% rGO/10% PPy exhibits exceptional conductivity due to the strong π-π stacking interaction between rGO and PPy. This interaction allows for the generation of a greater number of delocalized electrons within their structure, consequently reducing the hindrances to electron mobility and facilitating a more effortless flow of electrons. Moreover, within this composite, which comprises PPy and rGO, these effects are particularly pronounced. Therefore, MgFe2O4/10% rGO/10% PPy has the smallest activation energy among all samples (0.145 eV).
