Functional composite electromagnetic shielding materials for aerospace, electronics and wearable fields

Abstract

The rapid development of electronic equipment and communication system has led to the generation of large-scale electromagnetic pollution. Electromagnetic interference (EMI) shielding materials can effectively reduce the harm caused by EMI. However, electromagnetic shielding materials with universal functions cannot effectively exert their electromagnetic interference shielding performance in all fields. EMI shielding materials used in different fields must have specific functionality in their usage conditions. This paper, reviews the functional requirements, fabrication methods, and comprehensive properties of EMI shielding materials in aerospace, electronics, and wearable fields. Composite EMI shielding materials through structural design and raw material selection to obtain excellent functionality and efficient EMI shielding effectiveness. In addition, this paper presents the application prospects of adjustable composite EMI shielding and self-healing EMI shielding materials. We present the main challenges and prospects for future studies of composite EMI shielding materials based on careful consideration.
