Plant-Mediated Synthesis of Nickel-Doped Cobalt Oxide/Reduced Graphene Oxide Nanocomposites for Combined Antibacterial Activity and EMI Shielding.

ABSTRACT: The growing demand for environmentally conscious approaches in electromagnetic interference (EMI) mitigation has created interest in developing lightweight and multifunctional shielding materials synthesized through greener routes. In this study, nickel-doped cobalt oxide (Ni-d-Co) nanoparticles were synthesized via a plant-mediated method using Aloe barbadensis Miller phytoextract and integrated with reduced graphene oxide (RGO) to form RGO/Ni-d-Co epoxy nanocomposites. Structural, morphological, and spectroscopic analyses confirmed the successful doping of Ni²⁺ into Co₃O₄ and enhanced interfacial interaction with RGO sheets. The nanocomposites exhibited a marked enhancement in EMI shielding effectiveness, achieving ∼16.9 dB at 10 wt %
