Recent progress in morphological engineering of carbon materials for electromagnetic interference shielding

With the continuous development of information technology and electronic communications, the problems of electromagnetic interference (EMI) and electromagnetic wave pollution becomes more and more serious, and thus the EMI shielding materials have recently attracted numerous attentions. Carbon materials have been deemed as good candidate for novel EMI shielding materials due to their unique properties such as superior conductivity, light weight, stable chemical properties, good thermal properties, environmental friendliness, easy processing, and excellent mechanical properties. And great developments of carbon-based EMI shielding materials have been achieved in the past few years. In the current review article, we mainly focus on the EMI shielding mechanism and EMI shielding performance of various forms of carbon materials. Combining with the current research status, their future development was also prospected.
