New generation conductive coating - a shielding tool to resist electromagnetic wave interference

Conductive paint, as a coating with good conductivity, plays an important role in electromagnetic wave interference shielding. With the continuous advancement of technology, the interference of electromagnetic waves on people's lives and work is also increasing. In response to this issue, conductive paint has become an effective means of blocking electromagnetic waves due to its unique conductivity.

Whether it is household appliances, medical equipment, or military communication systems, they all face the problem of electromagnetic wave interference. For example, in the operating room of a hospital, the presence of strong electromagnetic waves may have an undeniable impact on medical equipment, even leading to surgical interruptions or erroneous results. By spraying or brushing conductive paint, non-metallic or non-conductive surfaces can absorb, conduct, and attenuate electromagnetic waves like metals, effectively shielding the interference of electromagnetic waves, ensuring the normal operation of medical equipment, and providing strong guarantees for the success of surgery.

In addition to medical equipment, conductive paint also has broad application prospects in fields such as aerospace and electronic communication. The interference of electromagnetic waves on navigation and communication systems has always been a challenge in spacecraft design. The emergence of conductive paint provides a completely new solution to this problem. By spraying conductive paint on the surface of spacecraft, electromagnetic wave interference from various sources such as the sun, earth, and lightning can be effectively shielded, improving the reliability and stability of navigation and communication systems.

The technical parameters of conductive coatings are also important criteria for evaluating their performance. According to the publication of technical parameters, the use of composite conductive particles has achieved a conductivity effect of ≤ 0.025 Ω/cm ², indicating that the conductivity of the conductive paint is excellent. The standard for applying conductive parameters is 1 Ω/20 μ m film thickness/distance of 10cm. This parameter indicates that even when the paint film reaches 20 μ m, the conductive ability of the conductive paint is still strong and can shield electromagnetic wave interference from within 10cm. Therefore, in practical applications, it is recommended to control the film thickness at 20-25 μ m to ensure the optimal performance of the conductive paint.

There is still much potential to be explored in the application of conductive paint. For example, conductive paint can be used for the casing of electronic products, effectively reducing the interference of electromagnetic waves on the interior of electronic devices, and improving their stability and reliability. In addition, conductive paint can also be widely used in the preparation of electromagnetic shielding materials. By coating conductive paint on fiber materials, efficient and flexible electromagnetic shielding materials can be prepared, which can be used in products such as anti-interference clothing and electromagnetic shielding curtains.

In summary, as a new generation of shielding material, conductive coatings have a very broad application prospect in the field of electromagnetic wave interference shielding. Through spraying, brushing, and other methods, conductive paint can make completely insulated non-metallic or non-conductive surfaces absorb, conduct, and attenuate electromagnetic waves like metals, shielding electromagnetic wave interference. In fields such as healthcare, aviation, and electronic communication, the application of conductive paint will provide strong support for the stable operation of related equipment. In the future, conductive paint has more potential waiting for us to explore, bringing more innovation and possibilities to the development of various industries.
