The working principle of carbon based absorbing materials is to cancel out heat and noise in the environment by absorbing electromagnetic waves

     Carbon based absorbing materialsIt is an absorbing material made of carbon material, usually used to absorb electromagnetic waves and eliminate their impact on the surrounding environment. Carbon based absorbing materials are one of the popular materials in absorbing materials, with many advantages such as high strength, low density, and excellent thermal insulation performance.

The main raw materials for carbon based absorbing materials include graphite, fibers, carbon felt, etc. Among them, graphite is one of the most common raw materials, which is widely used in aviation, aerospace, automotive and other fields due to its excellent mechanical and absorbing properties. Fiber is another commonly used raw material due to its advantages such as lightweight and breathability, and it also has a wide range of applications in the aerospace industry.

The working principle of carbon based absorbing materials is to counteract heat and noise in the environment by absorbing electromagnetic waves. When electromagnetic waves pass through carbon based absorbing materials, they interact with the active components in the carbon material, thereby absorbing the electromagnetic waves. Carbon based absorbing materials are usually divided into three categories, namely Metallic carbon based absorbing materialsNon metallic carbon based absorbing materials and Conductive polymer carbon based absorbing material.

Metallic carbon based absorbing materials refer to composite materials composed of metal nanoparticles and conductive polymers. This material has a high absorption frequency and good performance, such as low noise, high conductivity, etc. Commonly used metal nanoparticles include ferrite carbon black composites, ferrite graphite composites, metal nanoparticles conductive polymers, etc.

Non metallic carbon based absorbing materials refer to absorbing materials made of carbon materials. This material has the advantages of low density and high toughness, and is commonly used in the manufacturing of automotive insulation coatings and insulation parts in the aerospace industry.

Conductive polymer carbon based absorbing materials refer to absorbing materials composed of conductive polymers. This material has a high absorption frequency and good performance, and is commonly used in the manufacturing of electronic products and computer heat dissipation components.

In the practical application of carbon based absorbing materials, design and selection need to be based on specific application requirements. For example, in the aerospace field, carbon based absorbing materials can be used to eliminate the influence of electromagnetic waves on aircraft fuselage and wing structures; In the field of automobiles, carbon based absorbing materials can be used to eliminate the electromagnetic wave effects in car insulation layers and interior decoration systems; In the medical field, carbon based absorbing materials can be used to eliminate the impact of electromagnetic waves on medical equipment and precision instruments; In the military field, carbon based absorbing materials can be used to eliminate the impact of electromagnetic waves on weapon systems.

It should be noted that carbon based absorbing materials have some limitations, such as high density, low toughness, and poor high temperature resistance. At the same time, environmental protection and human health issues also need to be considered.
