Problems solved by technology

However, in practical application, on the one hand, it cannot detect the position of the infrared laser invasion point on the film in real time, and on the other hand, it cannot observe the imprint produced by the infrared laser invasion point.
In other words, the film is only passive protection, and it is not known whether there is actually any infrared laser intrusion, so it is not convenient to make targeted follow-up arrangements
In addition, the film can only protect against the leakage of infrared laser information, and it cannot effectively prevent the leakage of electromagnetic information

Abstract

The invention discloses a protective film for preventing infrared laser information leakage and electromagnetic information leakage. The protective film comprises a substrate layer; a conductive metal layer attached to the substrate layer in a sputter coating mode; a nanometer semiconductor layer attached to the conductive metal layer in a sputter coating mode; a nanometer heat-sensitive material layer attached to the nanometer semiconductor layer in a sputtering mode or a coating mode; a nanometer infrared absorption layer attached to the nanometer heat-sensitive material layer in a coating mode or a sputter coating mode; a nanometer photoluminescence layer bonded on the nanometer infrared absorption layer; a mounting adhesive layer adhered to the nano photoluminescence layer; and a protective layer adhered to the mounting adhesive layer. According to the invention, infrared laser information leakage and electromagnetic information leakage can be effectively prevented at the same time, and for infrared laser intrusion, the position of an infrared laser intrusion point on the protective film can be detected in real time, and an intrusion mark can be observed by naked eyes within a period of time after the intrusion infrared laser is removed.

Description
