The invention discloses a thermal control film with an energy selection characteristic for satellites, the thermal control film with the energy selection characteristic for satellites is of a multi-layer composite structure, the multi-layer composite structure comprises a thermal control protection layer, a substrate layer and an energy selection layer, the thermal control protection layer is attached to one side of the substrate layer, and the other side of the substrate layer is attached to the energy selection layer; the thermal control protection layer, the substrate layer and the energy selection layer are all of a thin film structure. The periodic structure of the diode is adopted on the energy selection layer, on one hand, the solar spectrum is emitted, the solar absorptivity of the thermal control film for the satellite with the energy selection characteristic is received, the thermal control performance is improved, on the other hand, the surface impedance characteristic of the energy selection layer can be changed according to the intensity of an incident electromagnetic signal, and the thermal control performance is improved. Therefore, the surface impedance characteristic of the thermal control film for the satellite with the energy selection characteristic is changed, the space strong electromagnetic environment protection capability of weak electromagnetic signal low-loss passing and strong electromagnetic signal suppression transmission is realized, and the defects in the prior art are overcome.
