Advanced Institute (Shenzhen) Technology Co., Ltd.: Overcoming the problem of long-term performance degradation of graphene absorbing materials

With the rapid development of electronic information technology, electromagnetic pollution and interference problems have become increasingly severe, and the research and development of absorbing materials has become the key to solving this problem. Graphene has shown great potential in the field of absorbing materials due to its significant advantages such as lightweight, high conductivity, large specific surface area, and strong dielectric loss. Advanced Institute (Shenzhen) Technology Co., Ltd. has been committed to the research and innovation of absorbing materials. However, the performance degradation problem of graphene absorbing materials during long-term use has become a major obstacle to their widespread application. This article will delve into how Advanced Institute (Shenzhen) Technology Co., Ltd. can respond to this challenge.

1、 Root cause analysis of performance degradation problem

（1） The impact of environmental factors

Under different environmental conditions for a long time, graphene absorbing materials will be eroded by various factors. In a humid environment, moisture can penetrate into the interior of the material, causing changes in the structure of graphene, affecting its conductivity and dielectric properties, and ultimately reducing its absorption capacity. In high-temperature environments, the chemical bonds inside the material may break, causing damage to the microstructure of the material and resulting in performance degradation. In addition, chemical corrosion is also an important factor. When exposed to corrosive gases or liquids, graphene will undergo chemical reactions with these substances, changing its chemical composition and physical properties.

（2） The stability of the material's own structure

The structure of graphene itself may undergo changes during long-term use. For example, the interaction between graphene layers may weaken, leading to changes in the stacking of layers and affecting the electromagnetic properties of the material. At the same time, the defects on the surface of graphene may gradually increase during use, and these defects will become the center of electron scattering, reducing the conductivity and absorption performance of the material.

（3） The effect of external stress

In practical applications,Graphene absorbing materialMay be subjected to various external stresses, such as mechanical vibration, compression, etc. These stresses can cause cracks or deformation in the material, damaging its internal conductive network and electromagnetic structure, resulting in a decrease in performance.

2、 Response strategy of Advanced Institute (Shenzhen) Technology Co., Ltd

（1） Optimize material preparation process

Advanced Institute (Shenzhen) Technology Co., Ltd. has improved the preparation method of graphene to enhance its crystal quality and structural stability. Advanced technologies such as chemical vapor deposition (CVD) are used to precisely control the growth conditions of graphene, reduce the generation of defects, and make graphene have a more complete crystal structure. At the same time, appropriate additives or surface modifications are introduced during the preparation process to enhance the interaction between graphene layers and improve the overall stability of the material. For example, doping graphene with stable elements such as nitrogen and boron can improve its electronic structure and chemical stability, and enhance its ability to resist environmental erosion.

（2） Design protective coating

In order to protect graphene absorbing materials from environmental factors, the company has developed a series of protective coatings. These coatings have good waterproof, moisture-proof, and corrosion-resistant properties, and can form a protective film on the surface of the material to prevent the invasion of moisture, oxygen, and corrosive substances. For example, using organic silicon coating, which has excellent water resistance and chemical stability, can effectively protect graphene absorbing materials. At the same time, protective coatings can also have a certain degree of flexibility, which can adapt to the deformation of materials under external stress, avoiding coating rupture and loss of protective effect.

（3） Building a composite structure

Composite graphene with other materials with good stability is an effective method to improve the long-term performance of absorbing materials. Advanced Institute (Shenzhen) Technology Co., Ltd. has constructed a composite structure with synergistic effects by combining graphene with materials such as ceramics and metals. Ceramic materials have advantages such as high hardness, high temperature resistance, and corrosion resistance, which can provide physical support and protection for graphene; Metal materials can improve the conductivity and magnetic properties of materials. By designing the composition and proportion of composite structures reasonably, the composite material can maintain stable absorption performance during long-term use. For example, by combining graphene with ferrite and combining the magnetic loss characteristics of ferrite with the dielectric loss characteristics of graphene, not only can the absorbing performance be improved, but the stability of the material can also be enhanced.

（4） Real time monitoring and maintenance

In order to promptly detect changes in the performance of graphene absorbing materials, Advanced Institute (Shenzhen) Technology Co., Ltd. has developed a real-time monitoring system. This system can monitor the electromagnetic properties, temperature, humidity and other parameters of materials in real time, and detect signs of performance degradation in a timely manner through data analysis. Once performance degradation is detected, the company can take corresponding maintenance measures based on monitoring results, such as repairing or replacing protective coatings, and heat treating materials to restore their structural stability.

3、 Future prospects

Advanced Institute (Shenzhen) Technology Co., LtdSignificant progress has been made in addressing the issue of long-term performance degradation of graphene absorbing materials, but there are still many challenges to be faced. In the future, the company will continue to increase research and development investment, conduct in-depth research on the performance degradation mechanism of graphene absorbing materials, and continuously optimize the preparation process and protective measures of materials. At the same time, we will strengthen cooperation with universities and research institutions, jointly explore new material systems and technological methods, and provide more solid technical support for the widespread application of graphene absorbing materials. We believe that with the unremitting efforts of Advanced Institute (Shenzhen) Technology Co., Ltd., graphene absorbing materials will play a more important role in the field of electromagnetic protection.
