摘要：
A low-loadMXene nanosheet/melamine composite spongeis preparedthrough an impregnation-rapid freeze-drying technique, enabling theMXene nanosheets to fully unfurl and organize onto an ordered 3D networkwithin the sponge's skeleton. The composite sponge exhibitshigh electrical conductivity (121 S m(-1)), in additionto possessing notable lightweight characteristics. Consequently, itattains significant electromagnetic interference (EMI) shielding effectiveness,peaking at 71 dB within the X-band, and showcases an excellent infraredstealth capability. This work not only underscores the immense potentialof MXene for EMI shielding but also broadens its potential applicationsin various fields.
