Is the attenuation characteristic of ultra-high permeability absorbing materials affected by external environment?

Brief introduction

Ultra high permeability absorbing materials have shown broad application prospects in fields such as electromagnetic compatibility (EMC), electromagnetic interference (EMI) suppression, radio frequency identification (RFID)/near field communication (NFC) metal interference resistance, and offshore wind turbine tower coating due to their unique electromagnetic properties. However, the performance of these materials in practical applications is often influenced by external environmental factors. This article will focus onResearch Platinum brand ultra-high magnetic permeability absorbing materialFor example, analyze the impact of external environment on its attenuation characteristics.

2、 Attenuation characteristics of ultra-high magnetic permeability absorbing materials

The attenuation characteristics of absorbing materials refer to their ability to absorb and attenuate electromagnetic waves. For ultra-high permeability absorbing materials, their attenuation characteristics mainly depend on the material's magnetic permeability and dielectric constant. A higher real part of magnetic permeability and dielectric constant represents a material with good energy storage capacity, while a higher imaginary part of magnetic permeability and dielectric constant represents a material with good loss capacity. By optimizing and adjusting the electromagnetic parameters of the absorbing material, excellent absorbing performance can be achieved.

3、 The influence of external environment on the attenuation characteristics of ultra-high permeability absorbing materials

3.1 Temperature Influence

Temperature is one of the important factors affecting the performance of absorbing materials. For ultra-high permeability absorbing materials, as the temperature increases, the molecular thermal motion inside the material intensifies, which may cause changes in magnetic permeability and dielectric constant, thereby affecting its attenuation characteristics. In addition, high temperature may also cause changes in the microstructure inside the material, such as lattice distortion, phase transition, etc., further affecting its electromagnetic properties.

3.2 Humidity impact

The influence of humidity on absorbing materials cannot be ignored. In high humidity environments, absorbing materials may absorb moisture, leading to changes in the internal microstructure of the material, such as increased porosity and enhanced interface effects, thereby affecting its electromagnetic properties. In addition, moisture may also act as a polarizing medium to participate in the attenuation process of electromagnetic waves, further altering the attenuation characteristics of the material.

3.3 Atmospheric Pollution

Particles and chemicals in air pollution may undergo chemical reactions or physical adsorption with the surface of absorbing materials, leading to changes in surface properties such as increased roughness and conductivity, thereby affecting their electromagnetic performance. In addition, air pollution may also affect the thermal stability, weather resistance, and other properties of absorbing materials.
