“…Electromagnetic shielding features rely on the inherent electron transference of materials [20]. It was observed that the material utilized for EMI shielding needs to be electron-conducting in nature, i.e., it needs to have mobile charge carriers [21]. When incident electromagnetic radiations interact with the mobile charge carriers of the conducting material, charges start flowing.…”

Electromagnetic interference disturbs the working of electronic devices and affects the surroundings and human health. Consequently, research has led to the development of radiation-protection materials. Inherently conducting polymers have been found to be suitable for electromagnetic interference (EMI) shielding owing to their fine electrical conductivity properties. Moreover, nanoparticle-reinforced conjugated polymers have been used to form efficient nanocomposites for EMI shielding. Nanoparticle addition has further enhanced the radiation protection capability of conducting polymers. This state-of-the-art comprehensive review describes the potential of conducting polymer nanocomposites for EMI shielding. Conducting polymers, such as polyaniline, polypyrrole, and polythiophene, have been widely used to form nanocomposites with carbon, metal, and inorganic nanoparticles. The EMI shielding effectiveness of conducting polymers and nanocomposites has been the focus of researchers. Moreover, the microscopic, mechanical, thermal, magnetic, electrical, dielectric, and permittivity properties of nanocomposites have been explored. Electrically conducting materials achieve high EMI shielding by absorbing and/or dissipating the electromagnetic field. The future of these nanomaterials relies on nanomaterial design, facile processing, and overcoming dispersion and processing challenges in this field.

The Zn0.5Cu0.5Fe2O4 nano ferrites were prepared by the solution combustion method using aloe vera gel. The polyaniline-Zn0.5Cu0.5Fe2O4 nano ferrite composites were prepared by Ex-situ polymerization method with different weight percentage ratio. The prepared samples were examined by X-Ray diffraction, SEM, EDAX, BET, TEM, VSM and Impedance analyser to investigate their structural, morphological, elemental analysis, average pore size and the porosity, magnetic, and dielectric properties, respectively. The cubic spinel structure was confirmed by X-ray diffraction patterns. Addition of PANI to zinc-copper nano ferrite exhibits shift in crystalline peaks towards larger angle. The existence of spherical and clumped particles was revealed by SEM examination. The retentivity and coercivity are determined and the magnetic moment values were decreases with increase in PANI to the ferrite nanocomposites. The ac conductivity constant at lower frequency and there is a sudden increase and decrease in its value as a function of frequency shows resonance behaviour. The CZF-1 (CZF 30%) composite shows highest ac conductivity and dielectric constant. The electromagnetic shielding interference studies were conducted for S-band frequency. The CZF-1 (CZF 30%) nano composite shows highest shielding effectiveness as compared to other composite in the frequency range 2 to 3 GHz. The experimental result showed that these materials are used for applications in electromagnetic interference shielding.
