Electromagnetic interference shielding thermoplastic composites reinforced with carbon based hybrid materials: a review

Abstract

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.
