Architecting Light-Weight, Flexible Thermoplastic Polyurethane Nanocomposites Embedded With Nickle-Doped Cobalt Ferrite Nanoparticles Alongwith Graphene For Excellent Electromagnetic Interference Shielding application

Popis výsledku v původním jazyce

The widespread usage of electronic applicances resulting in emission of EM radiations and further coupling and interference with the performance of the surrounding electronic devices has led to the emergence of need for electromagnetic shielding materials. In this work, Ni incorporated cobalt ferrite nanoparticles, NixC01-xFe2O4 (x= O, 0.33, 0.67) were synthesized utilizing the sonochemical synthesis raute. Further the synthesized NixC01-xFe2O4 (x= O, 0.33, 0.67) were incorporated along with electrically conducting filler Graphene in Thermoplastic Polyurethane matrix (TPU) by melt-mixing approach using microcompounder to developed three sets of nanocomposite sheets with 1 mm thickness. The structural, morphological and magnetic characteristics for NixC01-xFe2O4 (x= O, 0.33, 0.67) and their developed nanocomposites were comprehensively studied. The developed polymer nanocomposites were utilized for EMI shielding applications in the microwave range using wave-guide methodology. The influence of doping of Ni2+ ions in C0Fe2O4 nanoparticles was examined on the EMI shielding characteristics of the developed polymer nanocomposite. Electromagnetic parameters were comprehensively investigated to understand the correlation of complex permittivity, complex permeability, dielectric losses, magnetic losses, eddy current losses to the EMI shielding performance of the developed nanocomposites. The remarkable electromagnetic interference (EMI) shielding ability of nanocomposites is primarily attributed to their plentiful interfacial polarization, dipole relaxation, improved impedance matching condition, and the eddy current effect, and natural resonance in the developed polymer nanocomposite. The meticulously engineered nanocomposite, which is both lightweight and flexible, is highly suitable for practical application in several domains such as aviation, satellite, telecommunications, and radar stealth technology.
