Recent progress of metal electromagnetic shielding materials

Electromagnetic shielding is an important technique to suppress electromagnetic interference and realizes electromagnetic compatibility. Metal materials are currently the most widely used electromagnetic shielding materials. With the rapid development of 5G communication, Internet of things, intelligent consumer electronics and other related fields, the application of metal materials in electromagnetic shielding materials tends to become thin, broadband and multi-functional, which has attracted wide attention in recent years. In this paper, the recent development of metal and metal oxide electromagnetic shielding materials in the field of electromagnetic shielding is reviewed from the aspects of preparation, performance and application. The relationship among the composition of the material, the electromagnetic shielding efficiency, the thickness of the material and the applicable frequency is analyzed and introduced, and its future development trend is forecasted.
