Correlation analysis between the absorption performance of graphene absorbing materials and the content and number of graphene layers

With the rapid development of information technology, electromagnetic pollution has become an issue that cannot be ignored. In order to effectively address this challenge, the development of high-performance absorbing materials has become a research hotspot. Graphene, as a new type of two-dimensional nanomaterial, has shown great potential in the field of absorbing materials due to its unique physical and chemical properties. This article will focus on exploring the relationship between the absorption performance of graphene absorbing materials and their content and number of layers, and cite the work of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Graphene Absorbing MaterialsAs a research subject.

Characteristics of Graphene and Its Application in Absorbing Materials

Graphene is a two-dimensional material composed of a single layer of carbon atoms, with extremely high specific surface area, good conductivity, and thermal conductivity. These characteristics enable graphene toAbsorberIt can effectively absorb and dissipate electromagnetic wave energy. When graphene is combined with other matrix materials, it can form composite materials with excellent absorbing properties.

The relationship between absorption performance and graphene content

The content of graphene directly affects the absorption performance of composite materials. Generally speaking, increasing the content of graphene in moderation can improve the absorption efficiency of materials, as more graphene provides more interfaces and pathways for scattering and absorbing electromagnetic waves. However, excessive addition of graphene can lead to agglomeration within the material, which in turn reduces the absorption effect. according toAdvanced Institute (Shenzhen) Technology Co., LtdAccording to research data, when the mass fraction of graphene in the platinum brand graphene absorbing material increased from 1% to 5%, the maximum reflection loss value in the frequency range of 8-12 GHz increased from -15dB to -35dB; After increasing to 10%, the maximum reflection loss value slightly decreased, indicating the existence of an optimal graphene content range.

The relationship between absorption performance and graphene layer number

The number of graphene layers also affects the absorption performance of composite materials. Although single-layer graphene has the highest specific surface area and thinnest thickness, its absorption capacity is limited. Although multi-layer graphene reduces the specific surface area, it can enhance the overall absorption effect of the material by increasing the propagation path of electromagnetic waves. Research has shown that as the number of graphene layers in platinum brand graphene absorbing materials increases from 1 to 5, the material's absorption performance gradually improves; After exceeding 5 layers, the absorption performance tends to stabilize or even decrease. This indicates that a moderate increase in the number of layers is beneficial for improving the absorption performance.

Experimental verification and application cases

In order to verify the above theoretical analysis, Advanced Institute (Shenzhen) Technology Co., Ltd. conducted detailed experimental tests. The experimental results indicate that using graphene with 3-5 layers and a graphene mass fraction of 3% -5%Research Platinum Graphene Absorbing MaterialsThe average reflection loss in the X-band (8-12GHz) reached -25dB, demonstrating excellent absorption performance. This material has been successfully applied in multiple fields such as radar stealth coatings and electromagnetic compatibility design for communication equipment.

conclusion

In summary, the absorption performance of graphene absorbing materials is closely related to their content and number of layers. By controlling these two parameters reasonably, the absorption effect of the material can be significantly improved. In the future, with the advancement of graphene preparation technology and composite material processing technology, graphene absorbing materials will play an important role in more fields.
