Development and current situation of flexible and transparent EM shielding materials

The application of electromagnetic (EM) technology has greatly promoted the progress and development of society, and also brought the side effects of EM interference (EMI). In the fields of visualization windows, transparent wearable devices, and aerospace equipment, flexibility and transparency have become the performance requirements of EMI shielding materials. Materials such as metal-based materials, MXenes, carbon-based materials, and conductive polymers show the potential for flexibility and transparency and lots of cases have been developed. This article summarizes the flexible and transparent properties of mainstream EMI shielding materials, and evaluates their potential as flexible and transparent EMI shielding materials. Finally, the research progress of flexible and transparent EMI shielding materials based on different advanced technologies is summarized.
