The invention relates to the technical field of new materials, and discloses a new energy vehicle radiation shielding film which comprises a two-dimensional material composite structure, the shielding film comprises a two-dimensional material composite structure, and the two-dimensional material composite structure comprises a polyester fiber layer, an MXene layer and a transition metal sulfide layer. All the layers of materials are mutually combined through the interface enhancement layer to form a multi-layer composite film structure, the interface enhancement layer is a self-assembled monomolecular layer SAM, all the two-dimensional material layers are connected through hydrogen bonds, electrostatic interaction or covalent bonds, and the interlayer binding force and the overall stability are enhanced. The novel two-dimensional materials such as polyester fibers, MXene and transition metal sulfide are adopted, and the multi-layer composite structure design is adopted, so that the shielding film has excellent shielding effectiveness in a wide electromagnetic spectrum range. By accurately controlling the layer number, the thickness and the interface bonding mode of the material, high-efficiency absorption and reflection of low-frequency to high-frequency electromagnetic waves are realized.
