Lightweight and flexible 3D graphene microtubes membrane for high-efficiency electromagnetic-interference shielding

Ultralight, flexible and high-performance electromagnetic-interference (EMI) shielding performance materials are urgently required in the areas of aircraft/aerospace, portable and wearable smart electronics. Benefiting from the outstanding properties of graphene and the unique architectures, 3D assembled graphene structures have been widely applied in the field of EMI-shielding. Herein, for the first time, using Si3N4 nanowires as...
