Electromagnetic shielding materials and devices: a powerful tool for dealing with electromagnetic radiation

Imagine being in a room filled with electronic devices, do you often feel dizzy, disoriented, and even anxious? This is because electronic devices generate electromagnetic radiation, which poses potential hazards to the human body. To address this issue,electromagnetic shielding materialAnd devices have emerged, becoming an indispensable part of modern life.

1、 Electromagnetic radiation hazards

Electromagnetic radiation refers to the physical effects caused by electromagnetic fields, including the radiation of electromagnetic waves and the radiation of electrostatic fields. Electromagnetic radiation can have certain impacts on human health, such as causing discomfort such as headaches, drowsiness, dizziness, emotional anxiety, and even serious diseases such as cancer. Especially when people are exposed to electronic devices such as mobile phones and computers for a long time, their exposure to electromagnetic radiation is higher, and the harm to health is also greater.

2、 The role of electromagnetic shielding materials

Electromagnetic shielding materials refer to materials that can absorb, reflect, or scatter electromagnetic radiation. They play a role in shielding electromagnetic radiation by changing the propagation path of electromagnetic fields and absorbing the energy of electromagnetic waves. Common electromagnetic shielding materials include metal materials, conductive polymer materials, etc.

1. Metal materials

Metal materials have good conductivity and can effectively shield electromagnetic radiation. Among them, copper is the most commonly usedMetal shielding materialBecause it has good conductivity and plasticity, it can be used to make electromagnetic shielding covers and shielding doors. In addition, metal materials such as aluminum and steel can also be used for electromagnetic shielding, and the specific application needs to be selected according to different scenarios.

For example, in the operating room of a hospital, copper shielding covers are often used to protect patients and surgical instruments from electromagnetic radiation interference with electronic devices.

2. Conductive polymer materials

Conductive polymer material is a type of polymer material with conductivity and plasticity. Compared to metal materials, conductive polymer materials are lighter, softer, and have lower costs. Therefore, in certain situations, it is more appropriate to choose conductive polymer materials for electromagnetic shielding. It can be made into shielding clothing, shielding curtains and other products for human body protection and electronic device protection.

For example, in the aerospace field, astronauts wear shielding suits made of conductive polymer materials, which can effectively prevent electromagnetic radiation from interfering with spacecraft and astronauts.

3、 Application of Electromagnetic Shielding Devices

In addition to shielding materials, electromagnetic shielding devices are also important protective tools.

1. Shielding film

Shielding film is a thin film that can adhere to the surface of electronic devices, effectively shielding the entry and leakage of electromagnetic radiation. By selecting the appropriate oneShielding filmIt can reduce the impact of electromagnetic radiation on the human body and other electronic devices without affecting the normal operation of the equipment.

2. Filter

A filter is a device used to filter out specific frequency components in electromagnetic signals. It can help eliminate interference signals and make communication between devices more stable and reliable. The design and selection of filters need to be based on specific application scenarios and requirements.
