Zusammenfassung:The invention discloses a hydrogen bond driven type self-repairing wave-absorbing composite material and a preparation method thereof.A polyaniline/MXene composite material with good conductivity is prepared through an in-situ polymerization method, the polyaniline/MXene composite material serves as a wave-absorbing agent, a poly (acryloyl glycinamide) and polyvinyl alcohol double-crosslinking self-repairing network is constructed, and the hydrogen bond driven type self-repairing wave-absorbing composite material is prepared. The high-performance wave-absorbing material with self-repairing performance is obtained. According to the invention, the high conductivity and abundant surface functional groups of MXene are utilized, and the surface modification and interface design are carried out on the MXene through polyaniline, so that the composite wave-absorbing material with the lowest reflection loss value of-52 dB and the effective absorption bandwidth of 5.2 GHz is prepared. The polyvinyl alcohol matrix is en
