Abstract

The popularization of communication technologies has unfortunately resulted in electromagnetic wave pollution. Composites containing materials with different functionalities can help more effectively shield against electromagnetic waves. In this study, we synthesized a composite containing magnetic Fe₃O₄ nanoparticles on in situ-reduced graphene oxide (GO) nanosheets. The formation of the rGO–Fe₃O₄ composite was confirmed using field emission-scanning electron microscopy and X-ray diffraction. rGO–Fe₃O₄ nanosheets were mixed with a conductive polymer, namely poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), and coated and cured to produce a PEDOT:PSS/rGO–Fe₃O₄ film. The optimal shielding efficiency could reach −50 dB by appropriately setting the weight ratio and manufacturing parameters. With the total shielding effectiveness (SE_T) divided into reflection shielding effectiveness (SE_R) and absorption shielding effectiveness (SE_A), the produced thin film was found to be dominated by the absorption loss. The materials used in our composite are less environmentally polluting and have a simpler preparation process than conventional anti-electromagnetic products with metal particles. The composite has a 5G network band (3.5 GHz) and electromagnetic wave shielding capability. Our novel electromagnetic wave-resistant PEDOT:PSS/rGO–Fe₃O₄ film is a promising candidate for next-generation electromagnetic wave-resistant shield coatings.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
