Abstract

Today, people are exposed to radiation in their living and working environment. Electronic equipment and devices are widely used in various fields with the development of electronic science and technology. An excessive use of electronic devices leads to unwanted and undesirable byproduct, which is a novel kind of pollution called electromagnetic interference (EMI).  Although traditional metals and their alloys can serve as good electromagnetic shielding materials, their heavy weight, high cost as well as poor corrosion resistance limit their application in this field. Therefore, electromagnetic shielding materials with lightweight are gradually attracting more and more attention to meet the trend of lightweight and highly integrated electronic equipment. Polymer material and their composites have been used as EMI shielding materials due to their characteristics like lightweight, good corrosion resistance, and superior electrical, thermal, mechanical and magnetic properties. These lightweight materials with good EMI shielding performance will find more potential applications in communications, electronics, aerospace, military, etc. In this article, the phenomenon of electromagnetic interference and its type of shielding by polymer materials and its composites and their shielding effectiveness have been reviewed.
