Film system with selective electromagnetic shielding and high transmittance and preparation method thereof

The invention discloses a film layer system with selective electromagnetic shielding and high transmittance. The film layer system comprises a curved-surface optical window, an electromagnetic shielding functional film, an electrode film and an infrared antireflection film, the electromagnetic shielding functional film and the electrode film are the same in film system material, structure and thickness; the optical window adopts the curved surface, and the functional coating is prepared to the concave surface of the optical window and is sealed in the system, so that the same effect as that in the prior art is realized, external exposure of any functional coating is avoided, and damage of sand wind, rain erosion and radiation brought by an external environment to a film layer is thoroughly solved; and the resistance to severe environments such as high and low temperatures, damp and hot environments and the like is greatly improved. 本发明公开了一种具有选择性电磁屏蔽和高透过率的膜层系统，包括有曲面光学窗口、电磁屏蔽功能膜、电极膜和红外增透膜；所述电磁屏蔽功能膜与电极膜的膜系材料、结构和
