Electromagnetic shielding film is a transparent shielding material that can prevent electromagnetic waves from penetrating glass, resist electromagnetic radiation and interference

Shielding filmIt is a magical material that can block electromagnetic waves from penetrating glass, effectively reduce electromagnetic radiation, protect the security of electronic information, and resist electromagnetic interference. This transparent shielding material is deposited on a transparent polyester film by vacuum sputtering to form a highly conductive surface containing metals such as silver and copper. It can be directly attached to the surface of conventional glass or organic glass to achieve EMI electromagnetic interference shielding and electromagnetic radiation protection.

　　Electromagnetic shielding filmThe preparation technology is very advanced. In the process of manufacturing shielding film, the first step is to purify the material containing metal to ensure the purity of the film. Afterwards, the membrane is placed in a vacuum chamber and metal atoms are ejected onto the surface of the membrane using physical vapor deposition technology, forming a uniformly thick metal film. In this way, metal atoms can form a tightly arranged structure on the surface of the membrane, preventing electromagnetic waves from penetrating.

The material selection of shielding film is very important. Metal thin film is the key to achieving shielding effect, and metals with high conductivity and good stability are generally selected, such as silver, copper, etc. These metals have good conductivity and can effectively absorb and scatter electromagnetic waves. In addition, in order to improve the reliability and durability of the shielding film, a protective layer is usually added to the surface of the metal film to enhance its hardness and corrosion resistance, making it suitable for use in various harsh working environments.

The application of shielding film is very extensive. It can be applied in fields such as electronic devices, communication equipment, medical devices, military equipment, etc., providing strong electromagnetic radiation protection for these devices. In the field of electronic devices, electromagnetic shielding films can block the propagation of electromagnetic waves, protect the normal operation of devices, and prevent the leakage of electronic information. In the field of communication equipment, electromagnetic shielding film can effectively suppress electromagnetic interference and improve the communication quality of the system. In the field of medical devices, electromagnetic shielding films can prevent electromagnetic waves from causing harm to patients. In the field of military equipment, electromagnetic shielding film can protect sensitive equipment from electromagnetic interference, improve the reliability and safety of equipment.

The research and application prospects of electromagnetic shielding film are very broad. With the continuous progress and development of technology, people's requirements for electronic information security and electromagnetic radiation protection are also increasing. As a new type of technical material, shielding film has great potential for application. Future research will focus on improving shielding effectiveness, reducing the thickness and weight of shielding films, and lowering preparation costs.

In summary, electromagnetic shielding film is a type of material that can prevent electromagnetic waves from penetrating glass, resist electromagnetic radiation and interferenceTransparent shielding materialIt forms a metal thin film on the surface of the membrane through vacuum sputtering, achieving electromagnetic interference shielding and electromagnetic radiation protection. Shielding film has a wide range of application fields, which can protect the normal operation and safe work of electronic equipment, communication equipment, medical devices, military equipment and other equipment. With the development of technology, the research and application prospects of electromagnetic shielding films will become even broader, bringing more convenience and safety to people's lives and work.
