Graphene absorbing materials | Emerging forces at the forefront of technology and exploration by Advanced Institute (Shenzhen) Technology Co., Ltd

In today's era of rapid technological development, the application of electromagnetic waves is becoming increasingly widespread, from daily communication equipment to high-end aerospace fields, electromagnetic waves are everywhere. However, excessive radiation and interference of electromagnetic waves have also brought a series of problems, such as affecting the normal operation of electronic devices and potential harm to human health. Therefore, the research and application of absorbing materials have become crucial, and graphene absorbing materials, as an emerging force in this field, are attracting the attention of many research institutions and enterprises. Advanced Institute (Shenzhen) Technology Co., Ltd. is one of the outstanding players actively exploring.

Graphene: the ideal choice for absorbing materials

Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms in sp ² hybridized orbitals, forming a hexagonal honeycomb lattice. It has many unique physical and chemical properties, which make it an ideal raw material for preparing high-performance absorbing materials.

Firstly, graphene has an extremely high electron mobility, which means that electrons can move rapidly within it. When electromagnetic waves are incident on the surface of graphene, the electrons inside will quickly respond to the electric field changes of the electromagnetic waves, generating induced currents. This induced current will interact with the incident electromagnetic wave, converting the energy of the electromagnetic wave into other forms of energy such as thermal energy, thereby achieving the absorption effect. Moreover, the higher the electron mobility of graphene, the faster its response to electromagnetic waves and the better its absorption performance.

Secondly, graphene has a single atomic layer thickness and a large specific surface area. The thickness of a single atomic layer makes graphene have a short absorption path for electromagnetic waves in the direction perpendicular to the plane, which is beneficial for rapid absorption of electromagnetic waves. The larger specific surface area provides more opportunities for sufficient contact between electromagnetic waves and graphene, increasing the interaction area between electromagnetic waves and graphene, and further improving the absorption efficiency.

In addition, graphene also has good chemical stability and mechanical properties. It can maintain stable performance in various harsh environments and is not easily corroded or damaged, providing a guarantee for the long-term stability of graphene absorbing materials in practical applications. Meanwhile, its excellent mechanical properties also enable graphene absorbing materials to adapt to different shapes and structural requirements, making them easy to process and integrate into various devices.

Graphene electromagnetic shielding materialCurrent research status

In recent years, significant progress has been made in the research of graphene absorbing materials. Researchers have prepared various types of graphene absorbing materials using different methods and conducted in-depth research on their absorbing properties.

A common method is to composite graphene with other materials. For example, by combining graphene with magnetic materials such as ferrite and magnetic metal particles, the electrical loss characteristics of graphene and the magnetic loss characteristics of magnetic materials can be combined to achieve multi band absorption of electromagnetic waves. This composite material not only broadens the absorption frequency band, but also enhances the absorption intensity. In addition, combining graphene with polymer materials can improve the dispersibility and processability of graphene, while endowing absorbing materials with better flexibility and formability, making them more suitable for special applications.

In terms of preparation processes, various methods such as chemical vapor deposition (CVD), solution mixing, and in-situ growth are widely usedGraphene absorbing materialPreparation of. Different preparation methods will have a significant impact on the structure and properties of graphene, thereby affecting the final performance of absorbing materials. For example, CVD method can prepare high-quality and large-area graphene films, but the cost is relatively high; The solution mixing method is simple to operate and cost-effective, but the dispersibility of graphene may be poor. Therefore, researchers need to choose appropriate preparation methods based on specific application requirements.

Secondly, the performance stability of graphene absorbing materials needs to be further improved. Under different environmental conditions (such as temperature, humidity, corrosive environment, etc.), their absorbing performance may change, and more research is needed to improve their environmental adaptability. In addition, the standardization and normalization of graphene absorbing materials are relatively lagging behind, lacking unified quality standards and testing methods, which is not conducive to product quality control and market promotion.
