Absorbing materials play a crucial role in modern electronics, communication, and military fields. They can effectively absorb electromagnetic waves, reduce reflection and interference, thereby improving the performance and safety of the system. There are significant differences in composition, performance, and application fields among different types of absorbing materials. This article will focus on exploring the differences between carbon black absorbing materials and other types of absorbing materials, and introduce the products produced by Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand Carbon Black Absorbing Materials.

Carbon black absorbing material

Definition and Principle

Carbon black absorbing material is a type of absorbing material mainly composed of carbon black. Carbon black is a black powder composed of carbon elements, with a high specific surface area and good electrical conductivity. When electromagnetic waves enter the carbon black absorbing material, the carbon black particles absorb the electromagnetic wave energy and convert it into thermal energy, thereby achieving the effect of absorbing waves.

2. Lightweight: Carbon black absorbing materials have low density and are lightweight, making them suitable for applications with strict weight requirements.
3. Cost effectiveness: Carbon black raw materials are abundant and relatively low in price, making carbon black absorbing materials have a high cost-effectiveness.
4. Easy to process:Carbon black absorbing materialIt can be easily mixed with other materials and is suitable for various molding processes such as spraying, coating, and injection molding.

application area

Carbon black absorbing materials are widely used in fields such as radar stealth, electronic equipment shielding, antenna covers, and electromagnetic compatibility (EMC). Especially in the military field, carbon black absorbing materials are used to manufacture surface coatings for stealth aircraft, ships, and vehicles to reduce radar wave reflection and improve stealth performance.

Other types of absorbing materials

Metal based absorbing materials

Metal based absorbing materialsIt is mainly made of magnetic metals such as iron, nickel, cobalt, and their alloys. These materials have high magnetic permeability and conductivity, and can absorb electromagnetic waves over a wide frequency range. The advantage of metal based absorbing materials is excellent absorption performance, but the disadvantages are high density, heavy weight, and high cost.

Ceramic based absorbing materials

Ceramic based absorbing materialsIt is mainly made of ceramic materials such as ferrite and barium titanate. These materials have high dielectric constant and magnetic permeability, and can absorb electromagnetic waves within a specific frequency range. The advantages of ceramic based absorbing materials are good chemical stability and high temperature resistance, but the disadvantages are high brittleness and difficulty in processing.

Polymer based absorbing materials

Polymer based absorbing materials are mainly composed of polymer and conductive fillers (such as carbon fiber, graphene, etc.) composite. These materials have good flexibility and processability, making them suitable for various application scenarios. The advantages of polymer based absorbing materials are lightweight and low cost, but the disadvantage is relatively weak absorbing performance.

Graphene based absorbing materials

Graphene based absorbing materials are a new type of absorbing material composed of graphene and polymer materials. Graphene has a very high specific surface area and excellent conductivity, making graphene based absorbing materials have excellent absorbing properties over a wide frequency range. In addition, graphene based absorbing materials also have the characteristics of lightweight and flexibility, making them suitable for various application scenarios.
