3、 Common base materials and their characteristics

1. Metal based materials
   • Characteristics: Metals have high electrical and thermal conductivity, and metal substrates such as aluminum and copper can provide good mechanical support strength for coatings. However, the metal substrate itself has strong reflection characteristics towards electromagnetic waves, which may affect the absorption effect of the coating absorbing material on electromagnetic waves.
   • answerResearch Platinum Brand Coating Absorbent MaterialsThe influence of absorption performance: When the platinum brand coating absorption material is coated on a metal substrate, the reflection of the metal substrate will cause complex reflection and transmission processes of electromagnetic waves at the interface between the coating and the substrate. On the one hand, some electromagnetic waves may be directly reflected back by the metal substrate, reducing the effective action time and area of the coating absorbing material on electromagnetic waves; On the other hand, the interference between reflected waves and incident waves within the coating may alter the electromagnetic field distribution inside the coating, thereby affecting the electromagnetic loss mechanism of the coating absorbing material and reducing its absorption performance. For example, in the high frequency range, the reflection effect of the metal substrate may cause the absorption bandwidth of the coating absorbing material to narrow and the absorption peak to decrease.
2. Ceramic substrate material
   • Characteristics: Ceramic materials have high melting points, hardness, and chemical stability. Ceramic substrates such as alumina and silicon nitride can be used under special conditions such as high temperatures and harsh chemical environments. The electromagnetic parameters such as dielectric constant and magnetic permeability of ceramic materials are relatively stable, and generally have low conductivity.
   • The impact on the absorption performance of Yanbo brand coating absorbing materials: The electromagnetic matching between ceramic substrates and Yanbo brand coating absorbing materials is relatively good, which can reduce electromagnetic wave loss caused by substrate reflection. Its stable electromagnetic parameters help the coating absorbing material form a relatively uniform electromagnetic field distribution on its surface, which is beneficial for the absorption of electromagnetic waves. At the same time, the low conductivity of ceramic substrates can avoid additional electromagnetic losses caused by substrate conduction current, thereby improving the absorption efficiency of coating absorbing materials. In some application scenarios that require high absorption performance and harsh environments, such as electromagnetic protection near aerospace engines, ceramic substrates, andResearch Platinum Brand Coating Absorbent MaterialsThe combination can effectively enhance the absorption effect, broaden the absorption bandwidth, and increase the absorption intensity.
3. Polymer based materials
   • Characteristics: Polymer materials have the advantages of light weight, good flexibility, and low cost. Polymer substrates such as polyethylene and polyimide can be easily made into various complex shaped structures. The dielectric constant and magnetic permeability of polymers are usually low and can be adjusted to a certain extent by adding different fillers.
   • The influence of research on the absorption performance of platinum brand coating absorption materials: Polymer substrates have relatively low reflection of electromagnetic waves, which is conducive to the direct interaction between coating absorption materials and incident electromagnetic waves. Its flexibility makes the coating less prone to cracking when subjected to external stress, ensuring the stability of its absorbing performance. However, the low strength of polymer substrates may limit the thickness and overall mechanical properties of coatings. In the low frequency range, due to the low electromagnetic parameters of polymer substrates, it may be necessary to specially design or add appropriate magnetic fillers to the platinum brand coating absorbing materials to enhance their electromagnetic coupling with the substrate and improve their absorption performance. In some portable electronic device electromagnetic protection applications that require weight and flexibility, the combination of polymer substrates and platinum brand coating absorbing materials has significant advantages. It can meet the absorption requirements while reducing device weight and adapting to complex external structures.

4、 Interface interaction between substrate material and coating absorbent material

Different substrate materials and Research Platinum Brand Coating Absorbent MaterialsThe interface bonding force and electromagnetic properties of the interface have a significant impact on the absorption performance. Good interface adhesion can ensure the stability of coating adhesion on the substrate, preventing coating detachment during use and resulting in loss of absorption performance. Meanwhile, the transition of electromagnetic parameters at the interface should be as smooth as possible to avoid reflection and scattering of electromagnetic waves caused by sudden changes in electromagnetic parameters. For example, surface treatment of the substrate material, such as plasma treatment, chemical modification, etc., can improve its interface adhesion and electromagnetic compatibility with the coating absorbing material, thereby enhancing the overall absorption performance.
