    Electromagnetic interference shielding applications of poly-ether-ether-ketone (PEEK)-based hybrids and composites
    (Elsevier, 2025) Sezer Hicyilmaz, Ayse; Çelik Bedeloğlu, Ayşe
    With the advancement of technology, electromagnetic interference (EMI) and electromagnetic radiation pollution have become a serious global problem. Polymeric composites have been widely used as an alternative to metals for electromagnetic shielding, which is the most efficient material. Polyether ether ketone (PEEK) is a high-performance engineering polymer with outstanding mechanical, chemical, and thermal properties. It is frequently employed in industries that require EMI protection, such as aircraft, space exploration, and military. In recent years, a large number of studies on PEEK polymers with EMI shielding properties have been performed. These studies mainly focused on the preparation of the composites added with carbon-based or metal-based nanoparticles, carbon fibers, metal-coated carbon fibers, and hybrid additives in the PEEK polymer matrix or PEEK blends. This chapter reviews the representative additives in PEEK composites or blends, the preparation methods, and the EMI shielding properties. Moreover, the relationship between EMI shielding properties and other material properties is also discussed. The application of these composites in different industries and the expecting prospects in this emerging field are introduced. © 2026 Elsevier Inc. All rights reserved.

    Electromagnetic interference shielding thermoplastic composites reinforced with carbon based hybrid materials: a review
    (Taylor & Francis Ltd, 2022) Sezer Hicyilmaz, Ayse; Celik Bedeloglu, Ayse
    Parallel to the rapid technological developments in the electronics industry, electromagnetic (EM) interference protection has gained importance both daily and in all sectoral areas. Thermoplastic composites, which are widely used in electronic devices and vehicles, are becoming more popular due to their recyclability, superior mechanical/physical properties, the processability of complex shapes, and also blendability with various reinforcement materials compared to thermoset composites, and there has been an increasing demand for thermoplastic composites to have EM interference shielding properties. In this study, thermoplastic composites reinforced with carbon and metal hybrid filler systems produced by various production methods were investigated. Interfacial interactions of fillers and matrices were investigated by revealing synergistic EM interference shielding mechanisms. The effects of manufacturing processes, filler ratios, as well as the morphology of composites on EM interference shielding have been extensively discussed. The problems and limitations encountered in the production of EM interference shielding composites and the solution methods developed are emphasized. It is thought that this study will be a guiding resource for both academic and commercial studies.
