“…However, the obtained values for polymer film in Table 4 is notably higher than the previously reported conducting polymers. [46][47][48] Increase in AC conductivity of PANI by dispersing different weight percentage of SnO 2 NP was also reported by Rajeev Arora et al 49 In PANI/ SnO 2 composites, AC conductivity is very small in highfrequency region due to agglomeration of the NPs. On the other hand, it achieved a permittivity of the order of 600, which is stable only in low-frequency region.…”

Electrical conductivity is emerging as one of the most essential material's qualities of the 21st century due to the lightning‐fast advancements in the electronics sector and the continuously improving electrical goods. As conductive materials are used in the majority of the modern items we use, including power sources, energy generating systems, electrical circuits, sensors, and many others, continuing advancement in this field is very crucial. The novelty of this work lies in the dispersion of ferrite nanoparticles, which was synthesized using egg albumen to enhance the electrical behavior of PANI polymer films. In this research work, a simple casting approach was used to ex situ polymerize aniline to fabricate ultrathin and flexible CuFe2O4 distributed PANI films for electrical conductivity applications. The combustion approach was used to produce the copper ferrite nanoparticles, while egg albumen was not only used as the fuel but also it was used a capping agent to control the size of ferrite NPs with a size much lower than that already reported. Studies on the structural, morphological, and electrical properties of pure and various weight percent of (1 , 3 , and 5 wt%) CuFe2O4 loaded PANI films were performed. Comparing the different films, the 5 wt% CuFe2O4 dispersed PANI films exhibited remarkable and greatly improved permittivity and electrical conductivity with low dielectric loss. This indicates the 5 wt% CuFe2O4 dispersed PANI films have the prospective uses in high‐tech industries where there is a need for flexible, thin, and lightweight high electrical conducting materials with lesser loss factor.

“…Moreover, it is being water soluble, thus, would activate and stabilizes the dispersion of the nanofiller much easier. [19][20][21] In relation to the above remarks, we choose poly(anthranilic acid) (PANA), one of PANI derivatives with carboxylic acid group, as an alternative to the PANI. Despite of its low electro-active property 17,18,22 it possesses a high processibility and solubility in aqueous solutions, alcohol and polar solvents.…”

This research involves preparation and characterization of ternary hybrid nanocomposites; reduced graphene oxide rGO nanosheets, manganese dioxide MnO2 nanorods and poly (anthranilic acid) hollow sphere PANA (rGO-MnO2-PANA). The synthesis follows bi-step chemical reaction. Initially, rGO and MnO2 were prepared separately, then mixed together ultrasonically to form a binary hybrid of rGO-MnO2. Second step includes in situ polymerization of anthranilic acid monomer with the prepared rGO-MnO2. All the prepared compounds were characterized by different techniques: FT-IR, XRD, SEM, EDX and TEM. Incorporation of the ternary hybrid in different weight ratios with PVA afforded the required nanocomposites (rGO-MnO2-PANA/PVA) films. The electrical properties of the nanocomposite films were investigated at frequency of 10 kHz-2 MHz. It was found that, at low frequency, the dielectric (real) permittivity (ε’) and imaginary permittivity (ε”) approached to higher values in all cases, while these values decreased gradually with increasing frequency. It was also confirmed that the alternating current conductivity of the composites increased with increasing frequency. These findings underline the potential employing of rGO-MnO2-PANA/PVA composites as a flexible dielectric material for enhancing polymer electrical conductivity and in energy storage applications.
