How to improve the low-frequency absorption effect of rubber patch type absorbing materials?

Rubber patch type absorbing materialIn order to improve the absorption effect in the low frequency range, it is necessary to comprehensively consider multiple factors such as material design, preparation process, and application environment. Here are some key strategies and methods:

1. Optimize the selection and formulation of absorbers

Types of absorbers: The key is to choose absorbers that have significant absorption effects on low-frequency electromagnetic waves. For example, carbonyl iron powder exhibits excellent absorption performance in the low frequency range due to its high magnetic permeability and magnetic loss characteristics. Meanwhile, new carbon materials such as carbon nanotubes and graphene have also attracted attention due to their unique electromagnetic properties.

Formula adjustment: By adjusting the content, particle size distribution, and shape of the absorber (such as flattening), the electromagnetic parameters of the material can be optimized to improve the absorption effect in the low-frequency range. Research has shown that increasing the flatness of the absorber appropriately can shift the absorption peak towards lower frequencies and enhance the absorption intensity in the low frequency range.

2. Adjust material thickness and structure

Thickness optimization: There is an optimal matching relationship between the absorption performance of absorbing materials and their thickness. For low-frequency electromagnetic waves, thicker materials often provide better absorption effects. Therefore, by adjustingRubber patch type absorbing materialThe thickness can better match the absorption requirements of low-frequency electromagnetic waves.

Multi layer structure design: Adopting a multi-layer structure design, multiple reflections and absorption of low-frequency electromagnetic waves can be achieved by matching the electromagnetic parameters of different layer materials, thereby improving the overall absorption efficiency.

3. Improve material interface bonding and conductive network

Interface bonding: Ensuring a good interface bonding between the absorber and the rubber substrate helps to improve the transmission and attenuation efficiency of electromagnetic waves inside the material. By appropriate surface treatment or adding surfactants, the interfacial bonding performance can be improved.

Conductive network construction: Constructing a conductive network in rubber substrates, such as adding conductive fillers or using conductive polymers, can improve the conductivity of the material and enhance its ability to absorb electromagnetic waves. The uniformity and connectivity of conductive networks have a significant impact on the low-frequency absorption effect.

4. Adaptive design for application environment

Temperature and humidity adaptability:Rubber patch type absorbing materialDuring use, it may be affected by environmental factors such as temperature and humidity. Therefore, in the design process, it is necessary to consider the temperature stability and moisture resistance of the material to ensure that it can maintain good absorption performance even in harsh environments.

Electromagnetic environment adaptability: For specific electromagnetic environments, such as those with strong reflection sources or complex electromagnetic interference, the electromagnetic parameters and structural layout of materials can be adjusted to better adapt to environmental requirements and improve the low-frequency absorption effect.
