Polycrystalline iron fiber suction material is a new type of suction material with a wide absorption frequency band and a better absorption effect.


1. Principles of polycrystalline iron fiber suction material:


The polycrystalline iron fiber suction material uses its porous structure and conductive performance to produce multiple reflection, scattering and absorption under the action of electromagnetic waves, thereby achieving the absorption and attenuation of the electromagnetic wave.


2. Advantages of polycrystalline iron fiber suction materials:


(1) Broadband absorption: The polycrystalline iron fiber suction material has a good absorption effect on the electromagnetic waves of each band, which can achieve a more comprehensive electromagnetic wave absorption.


(2) Good anti -high temperature performance: Polycrystalline iron fiber suction material has a good high temperature resistance, and can still maintain a good suction performance in high temperature environments.


(3) Structural adjustability: The pore structure and fiber form of polycrystalline iron fiber suction material can be regulated through the appropriate process to meet the absorption requirements of different frequencies.


3. Application of polycrystalline iron fiber suction materials:


Polycrystalline iron fiber suction materials have extensive application prospects in radar, communication, electronic interference, electromagnetic wave stealth and other fields. For example, stealth shells that can be used to make military equipment such as ships, aircraft, missiles, and missiles can effectively reduce the probability of electromagnetic radiation and detection.


4. How to prepare polycrystalline iron fiber suction materials:


There are many ways to prepare polycrystalline iron fiber suction materials. The common methods mainly include the solution-gel method, electrochemical deposition method, thermal treatment method, etc. According to different requirements and practical applications, you can choose the appropriate preparation method.


5. Research progress of polycrystalline iron fiber suction material:


The study of polycrystalline iron fiber suction materials has been continuously deepened and promoted, and scholars in related fields are committed to improving research in the field of absorption and expanding applications. At present, some important research results have been achieved, and it has provided a good foundation for the development of related fields.
