摘要
With the rapid development of wireless communication and electronic devices, current electromagnetic interference (EMI) shielding materials cannot meet the demands of smart EMI shielding in the next generation of electronic equipment. Herein, we developed an intelligent EMI shielding switch to realize microwave shielding and transmitting functions for one material simultaneously. The EMI shielding switch is composed of MXene/melamine sponge, and 3D printed resin base. The EMI shielding switch can smartly regulate its absorption-dominant EMI SE from ~0 dB to ~43.1 dB in S-band through simply operation, to fully realize microwave transmitting and shielding functions simultaneously. The EMI shielding switch provides a novel way to fabricate efficient EMI shielding materials for actual wireless communication demands.
