Electromagnetic Interference Shielding Materials for Aerospace Application

Summary

Electromagnetic interference (EMI) is a critical problem that originates from either outside or inside an airplane or space vehicles. In addition, EMI is an undesirable electromagnetic wave that makes trouble for electronic devices, disturbing their operation. The EMI shielding materials can show the better electromagnetic shielding performance for the various applications, including equipment and devices in various field such as aerospace‐aeronautic, electrical, electronics, military, communication, and home appliances. Low intensity radiated fields are generated from blue tooth devices, mobile phones, laptop, tablets and wireless accessories. A high intensity radiated field can either be engendered by mankind or occur naturally. There are two ways to obtain the effective shielding. One is active shielding and the other is passive shielding at low frequency electromagnetic fields. This chapter covers the topic of polymer composites for EMI shielding. It introduces the properties and characteristics of carbon nanotubes in order to describe the advantage of carbon nanotubes based polymer composites.
