Abstract

A low-load MXene nanosheet/melamine composite sponge is prepared through an impregnation-rapid freeze-drying technique, enabling the MXene nanosheets to fully unfurl and organize onto an ordered 3D network within the sponge’s skeleton. The composite sponge exhibits high electrical conductivity (121 S m^-1), in addition to possessing notable lightweight characteristics. Consequently, it attains significant electromagnetic interference (EMI) shielding effectiveness, peaking at 71 dB within the X-band, and showcases an excellent infrared stealth capability. This work not only underscores the immense potential of MXene for EMI shielding but also broadens its potential applications in various fields.
