▎ 摘　　要

In this work, electrothermal-driven shape memory graphene fiber felt/carbon fiber felt/ethylene-co-vinyl acetate (GFF/CFF/EVA) EMI shielding composites were prepared via hotpress. The electromagnetic interference shielding effectiveness (EMI SE) of the GFF/CFF/EVA composites in X-band can reach 58.8 dB. Moreover, the shape memory fixity ratio and recovery ratio of the composites were 99 % and 95 %, respectively.
