Abstract

Because of the wide use of commercial, military, and scientific electronic devices and communication instruments, electromagnetic interference (EMI) shielding of radio frequency radiation continues to be a serious concern for modern society. The preparation of EMI shielding materials has obtained an increased attention in the academic and industrial field. Compared to the conventional metal-based EMI materials, polymer conposites containing carbon-based nanofillers have their own advantages, such as being lightweight, resistance to corrosion, excellent processability, and broad absorption bandwith and flexible. Graphene, a new class of 2D carbon nanomaterials, possesses extraordinary electrical, mechanical, and thermal properties. These unique features offer great promise for its use in EMI shielding. Besides, for the application in special fields such as aerospace, weapon equipment, military protection, vehicles and microelectronics where the materials with superior thermal stability, excellent mechanical properties, perfect radiation, and electrical resistant performance are required, high performance graphene composites could be a better candidate to fulfill the task. In this review, EMI shielding graphene based composite were classified by the method of graphene preparation.
