Graphite absorbing material

Graphite suction material is a material with higher frequency bandwidth and suction performance, which is often used in the field of electromagnetic wave absorption.

1. Principles of graphite suction materials: Graphite suction materials use the internal conductive loss and magnetic losses inside the material to absorb electromagnetic waves. Graphite itself has high conductivity and magnetic conductivity, showing good suction characteristics within a high frequency range.

2. Preparation of graphite suction materials: There are two main methods for preparing graphite suction materials. One is to mix the graphite powder directly with the polymer matrix, and then add the corresponding filler Or graphene and polymer matrix are prepared.

3. The performance characteristics of graphite suction materials: Graphite suction materials have broadband band characteristics and high suction performance. It can achieve lower reflection and transmission loss in the electromagnetic wave band, and can effectively reduce the reflection and scattering of electromagnetic waves.

4. Application of graphite suction materials: Graphite suction materials are widely used in the field of electromagnetic wave absorption, such as communication equipment, radar systems, electronic equipment, etc. It can effectively reduce the interference of electromagnetic waves to equipment and improve the work performance of the equipment.

5. The development trend of graphite suction materials: At present, the preparation methods and performance of graphite suction materials are continuously improved and improved. As an emerging material, graphene has excellent conductivity and suction performance, and is considered one of the research hotspots of graphite suction materials.
