In a wide range of applications, from consumer electronics to cutting‐edge industrial and scientific equipment, high dielectric permittivity (ε′) polymers are crucial for maximizing the performance and efficiency of electrical and electronic systems. Researchers strive to create and perfect these materials to meet the changing demands of modern technology. It is generally known that freestanding bare polymers cannot achieve high dielectric values; however, the mixing of multiple materials that are distinct is an effective technique for developing high dielectric hybrids. Polymer‐based nanoarchitectures are particularly beneficial for use in the storage of energy due to characteristics such as excellent mechanical strength, noncorrosive nature, lightweight, affordability, versatility, thermal and electrical shielding. The primary aim of this investigation is to prepare copper ferrite, zinc ferrite, and copper0.5 zinc0.5 ferrite (CuFe2O4, ZnFe2O4, and Cu0.5Zn0.5Fe2O4) nanoparticle (NP) via combustion technique using egg albumen as a fuel and these NPs were separately dispersed in polyaniline (PANI) matrix by the method of ex situ polymerization of aniline with an objective to enhance the electrical properties for energy storage and electromagnetic wave applications. Flexible freestanding films were casted via solution casting technique. X‐ray diffractogram of 5 wt.% NP dispersed PANI films confirmed the presence of NPs in the PANI matrix. Scanning electron micrograph images show the homogeneous dispersion of NPs into PANI matrix. Rather than the pure ferrite NPs, mixed ferrite highly enhance the permittivity of PANI films without much increasing its loss factor, the obtained values of ε′ of all the three ferrite added films are higher than polyvinylidene fluoride (PVDF)/(Mn0.2Zr0.2Cu0.2Ca0.2Ni0.2)Fe2O4 nanofiller. In this work notably for 5 wt.% Cu0.5Zn0.5Fe2O4 dispersed film shows the highest value of ε′ (7291) for 100 Hz at 150°C with ultralow loss factor (0.08) which is the key characteristic of an energy storage material. Thus, this present study leads the formation of a cost effective, flexible, high dielectric material, which can be a potential alternate to replace PVDF/(Mn0.2Zr0.2Cu0.2Ca0.2Ni0.2)Fe2O4 and polyvinyl alcohol/Ni0.65Cu0.35Fe2O4 polymer blends for energy storage applications.

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.
