Progress in Research on Lightweight Graphene-based EMI Shielding Materials
Abstract
With rapid progresses on the advanced electronic science and technology, electromagnetic irradiations have led to considerable issues, including electromagnetic pollutions, electromagnetic interference and security concerns, in electronics, aeronautics, astronautics, information technology, communication systems and etc. Based on the fundamentals of the electromagnetic interference shielding and general methods for preparing graphene nanosheets, this review involves the recent advances in the electromagnetic interference shielding materials of various applications in four morphologies, which include bulk, lightweight foams, flexible films and those for operation at high temperature. Meanwhile, the major strategical methods and general concept for designing and fabricating graphene-based electromagnetic interference shielding materials have been overviewed, and fundamental issues of electromagnetic interference technology have been further discussed. The perspectives for fabricating novel electromagnetic interference shielding materials, including ultrathin and transparent configuration, and future development have been proposed based on the practical applications, which suggest significant conception for designing next generation lightweight EMI shielding materials.
