The invention relates to the technical field of electromagnetic wave absorbing materials, in particular to a wave-absorbing printing paste, a flexible light composite wave-absorbing fabric and a preparation method and application of the flexible light composite wave-absorbing fabric. The soft and light graphene-coated MXene-coated Fe3O4 composite wave-absorbing fabric integrated with antibiosis is prepared by adopting a simple one-step method, graphene provides dielectric loss, MXene constructs a conductive network on staggered fibers to adjust impedance matching, and meanwhile, a magnetic material Fe3O4 is introduced to further improve impedance matching and increase magnetic loss. Besides, abundant interfaces exist among the three materials and between the materials and the fabric, interface polarization can be generated, the wave-absorbing performance is further enhanced, the method is more environmentally friendly and easy and convenient to operate, and a new thought is provided for ...
