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.

    本发明公开了一种具有能量选择特性的卫星用热控薄膜,具有能量选择特性的卫星用热控薄膜为多层复合结构,多层复合结构包括热控防护层、基底层和能量选择层,热控防护层与基底层的一侧贴合,基底层的另一侧与能量选择层贴合;热控防护层、基底层和能量选择层均为薄膜结构。本发明提出的在能量选择层上采用二极管的周期性结构,一方面发射太阳光谱,接收具有能量选择特性的卫星用热控薄膜的太阳吸收率,提升热控性能,另一方面能量选择层可以根据入射电磁信号的强弱而改变自身的表面阻抗特性,进而改变具有能量选择特性的卫星用热控薄膜的表面阻抗特性,实现弱电磁信号低损通过和强电磁信号抑制传输的空间强电磁环境防护能力,解决了现有技术的不足。
