Exploring shielding materials: a powerful tool to resist interference

Introduction: With the promotion of modern high-tech technology, people's attention to electromagnetic interference is also increasing. Shielding materials, as a powerful tool to solve electromagnetic interference problems, are widely used in various fields.Advanced Institute of TechnologyThis article will introduce several common shielding materials to help readers better understand the types and functions of shielding materials.

1、 Metal shielding materials: the first line of defense for protecting electronic devices

Metal shielding materialIt is one of the earliest used shielding materials, playing an important role in shielding interference with its excellent conductivity and electromagnetic wave reflection characteristics.

1. Copper shielding material: As one of the most common metal shielding materials, copper provides strong reflection shielding function for electromagnetic waves with its good conductivity and refractive index. It is commonly used in the shielding layer of electronic devices and circuit boards.

2. Aluminum shielding material: Similar to copper, aluminum also has good conductivity and electromagnetic wave reflection properties. According to the requirements, aluminum shielding materials can be further subdivided into different forms such as pure aluminum film, aluminum foil, aluminum mesh, etc., which can be applied to different shielding needs in different scenarios.

2、 Conductive rubber material: soft protective barrier

Conductive rubber materialDue to its soft and durable characteristics, it has become an important member of shielding materials, suitable for scenarios that require bending, squeezing, and twisting.

1. Conductive silicone: made by mixing conductive agents with silicone, it has excellent conductivity, wave conductivity, and oxidation resistance. Conductive silicone is widely used in electronic components, electromagnetic shielding rooms, and other scenarios.

2. Silver adhesive: Silver adhesive is a material with excellent conductivity and thermal conductivity, widely used for bonding and shielding electronic components.

3、 Carbon fiber material: a lightweight and efficient shielding choice

Carbon fiber materialDue to its lightweight and high-strength characteristics, it has become a new favorite in the field of shielding materials, especially suitable for scenarios with strict weight requirements.

1. Carbon fiber gauze: Made from high-purity carbon fiber spun into yarn, it has good conductivity and wave guiding properties, and is widely used for electromagnetic shielding and electrostatic protection.

2. Carbon fiber composite materials: By combining carbon fiber with base materials, multi-layer and multifunctional shielding materials can be produced, which not only have excellent shielding performance, but also good mechanical properties and corrosion resistance.
