Abstract:
Conducting polymer composites have emerged as promising materials for electromagnetic interference (EMI) shielding in satellite applications due to their lightweight, flexibility, and high shielding effectiveness. Recent advances focus on synthesizing composites with multilayer or three-dimensional conductive networks, which significantly enhance EMI shielding by promoting both absorption and reflection of electromagnetic waves. The incorporation of conductive fillers such as carbon nanotubes, graphene, or metallic nanowires into polymer matrices enables the formation of efficient conductive pathways, crucial for high-performance shielding. These materials offer advantages over traditional metal-based shields, including corrosion resistance, ease of processing, and design versatility, making them ideal for aerospace and satellite environments. Despite their potential, challenges remain in optimizing the interface compatibility and mechanical durability of layered structures for reliable long-term operation in demanding satellite conditions.

Abstract:
Electromagnetic interference shielding effectiveness (EMI-SE) measurement setups typically use two antennas placed on opposite sides of the test sample—one as a transmitter connected to a signal generator, and the other as a receiver to measure the attenuated signal. Advanced setups may utilize vector network analyzers for precise and rapid characterization. These methods enable reliable assessment of shielding materials for applications sensitive to electromagnetic interference.

Abstract:
Electromagnetic interference (EMI) poses significant challenges to electronic device performance and human health due to increased electromagnetic pollution. Conducting polymer nan composites have emerged as promising materials for EMI shielding owing to their tunable electrical conductivity and strong microwave absorption capabilities. Incorporating nanoparticles into conducting polymers enhances their shielding efficiency by improving electrical, mechanical, and absorption properties. These nanocomposites, based on polymers like polyaniline, polypyrrole, and polythiophene, offer flexile, lightweight, and robust solutions for shielding in telecommunications, aerospace, and military applications. Ongoing research focuses on optimizing composite microstructures and filler interactions to develop next-generation EMI shielding materials with superior performance and multifunctionality
