As an important component of EMI electromagnetic shielding materials, absorbing materials will play an increasingly important role in future development

The application of EMI electromagnetic shielding materials is becoming increasingly widespread in high-tech fields, especially in communication, electronic equipment manufacturing, aerospace and other fields. EMI electromagnetic shielding materials can not only effectively shield external electromagnetic interference, improve equipment stability and performance, but also protect the human body from the harm of electromagnetic radiation to health. In order to achieve better EMI electromagnetic shielding effect, absorbing materials play a crucial role.

Absorbing material is a special material that can consume electromagnetic wave energy and convert it into thermal energy. By absorbing and attenuating electromagnetic waves, it achieves effective isolation of electromagnetic waves. In EMI electromagnetic shielding, absorbing materials can effectively reduce the reflection and transmission of electromagnetic waves, improving the shielding effect. Meanwhile, the unique structure and composition of absorbing materials also determine their absorption performance and applicability in different frequency bands.

Types and application fields of absorbing materials

Absorbing materials can be classified according to their structure and material propertiesSoft magnetic absorbing materials, composite absorbing materials, metal based absorbing materialsWaiting for various types. Various absorbing materials have their unique advantages in different frequency bands and application scenarios. For example, soft magnetic absorbing materials have good absorption performance in the low frequency range and are suitable for EMI shielding in power systems and low-frequency communication equipment; Composite absorbing materials have excellent absorption performance in the high frequency range and can be used for EMI shielding in radar systems and high-frequency communication equipment.

It is worth mentioning that with the continuous development and popularization of 5G technology, higher requirements have been put forward for EMI electromagnetic shielding materials. The special nature of 5G communication frequency bands requires absorbing materials to have better absorption performance and stability at higher frequencies to ensure the normal operation of communication equipment and human health and safety.

Research and application of absorbing materials

At present, the research and development of absorbing materials has become one of the hotspots in the field of cutting-edge technology. Many research institutions and enterprises have invested a large amount of resources in the research and development of new absorbing materials, striving to improve their absorbing performance and expand their application scope.

Taking Laird, an American company, as an example, the company has not only achieved good results in improving traditional absorbing materials, but also has unique advantages in the research of new materials. The flexible graphene absorbing material developed by it achieves effective absorption and shielding of extremely high frequency electromagnetic waves through the conductive and absorbing properties of graphene, and is widely used in 5G communication equipment and aerospace fields, highly recognized by the market.

The future development trend of absorbing materials

With the continuous advancement of technology and the expansion of application fields, absorbing materials will usher in a broader development space. In the future, with the rapid development of new technologies such as artificial intelligence, the Internet of Things, and intelligent manufacturing, the demand for EMI electromagnetic shielding materials will continue to grow.

In this context, absorbing materials need to constantly innovate and upgrade to adapt to more complex electromagnetic environments and diverse application scenarios. Future absorbing materials may develop towards high efficiency, lightweight, and multifunctionality, providing more comprehensive and reliable solutions for EMI shielding problems in various industries.
