High-Performance, Lightweight, and Flexible Thermoplastic Polyurethane Nanocomposites with Zn²⁺-Substituted CoFe₂O₄ Nanoparticles and Reduced Graphene Oxide as Shielding Materials against Electromagnetic Pollution.

ABSTRACT: The development of flexible, lightweight, and thin high-performance electromagnetic interference shielding materials is urgently needed for the protection of humans, the environment, and electronic devices against electromagnetic radiation. To achieve this, the spinel ferrite nanoparticles CoFe₂O₄ (CZ1), Co_0.67Zn_0.33Fe₂O₄ (CZ2), and Co_0.33Zn_0.67Fe₂O₄ (CZ3) were prepared by the sonochemical synthesis method. Further, these prepared spinel ferrite nanoparticles and reduced graphene oxide (rGO) were embedded in a thermoplastic polyurethane (TPU) matrix. The maximum electromagnetic interference (EMI) total shielding effectiveness (SE_T) values in the frequency range 8.2-12.4
