    Transparent shielding filmIt is a new type of material with characteristics such as transparency, conductivity, and shielding. It can be widely applied in fields such as electronics, communication, aerospace, and healthcare. This article will introduce the preparation methods, performance characteristics, and application fields of transparent shielding films.

1、 The preparation method of transparent shielding film mainly includes the following steps:

1. The substrate for preparing transparent shielding film can be selected from transparent plastics such as PET, PC, PMMA, etc. The surface of the substrate needs to be cleaned, dusted, and anti-static treated to ensure surface smoothness and adhesion.
2. The preparation of conductive coatings involves forming a conductive layer on the surface of the substrate through methods such as vacuum evaporation and sputtering. The conductive layer can be made of materials such as ITO (indium tin oxide) and AZO (aluminum zinc oxide). The thickness of the conductive layer should be controlled according to actual needs, generally between 50-200nm.
3. The preparation of the shielding layer forms a shielding layer on the surface of the conductive layer. The shielding layer can be made of materials such as Ni, Ag, Cu, etc. The thickness of the shielding layer should be controlled according to actual needs, generally between 10-50nm.

4. After processing through conductive and shielding layersTransparent shielding filmPost processing is required, including cleaning, drying, trimming, and other processes.
   

2、 The performance characteristics of transparent shielding film are as follows:

1. The substrate of the transparent shielding film with high transparency is transparent plastic, and both the conductive layer and the shielding layer are thin films. Therefore, the transparent shielding film has high transparency, which can reach 80%! On (MISS).
2. The conductive layer of the transparent shielding film with good conductivity is made of materials such as ITO and AZO, which have excellent conductivity and are superior to traditional metal mesh conductive films in terms of conductivity.
3. The shielding layer of transparent shielding film can effectively shield electromagnetic waves and has good shielding performance.
4. The substrate of transparent shielding film with good bendability is transparent plastic, which has good bendability and can be made into conductive devices of various shapes.

5. The transparent shielding film has good heat resistance and can work normally in high temperature environments.
