If you are looking for a way to shield your electronics from EMFs, you might wonder about the additional EMF shielding materials. You can choose from Foam, Silicone, Graphite, and Fabric. These materials all have their advantages and disadvantages. Read on to learn more about them.
Fabric
Fabric for EMF shielding purposes is made from specially treated materials, such as copper and nickel. These materials resist the electromagnetic fields produced by cell phones and other electronic devices. In addition, these materials can be washed in a washing machine and are ironable. However, it is essential to be careful when cleaning this fabric. The fabric can be damaged if put in the dryer. Therefore, it is advisable to only machine-wash and dries it after use.
Electromagnetic radiations emitted from electronics are harmful to human tissue.
Furthermore, they can interfere with bio-electronic devices, such as pacemakers. This has increased the demand for garments that shield the user from electromagnetic fields. Electromagnetic shielding fabrics are now available to meet this demand.
Graphite
Graphite is a highly flexible material that has excellent EMI shielding properties. It is also resistant to heat, flame, and chemicals. Graphite also has very low creep relaxation to maintain its structure even under compression. As a result, graphite is used as an EMI shielding material for electronics.
Graphite can also be used in the film to shield electronic devices from electromagnetic radiation. However, the current processes to make graphite films require high temperatures and several hours of processing. Recently, Chinese researchers demonstrated an alternative method for making graphite films. These films are grown by quenching hot strips of nickel foil in ethanol. This method is more effective than current methods and yields films with the same electrical conductivity and mechanical strength as films made by chemical vapor deposition.
Nickel-coated Carbon Fiber-Incorporated SR
A wide range of carbon and graphite fibers is conductive enough to be used in various applications. These fibers may be coated with different metals. For example, graphite and carbon fibers with a silver or nickel coating are exciting. A mixture of fibers is also possible.
This compound has an average length of 6.35 mm. Its shielding power increases if the carbon fibers are more prominent in size. The nickel-coated carbon fibers are more effective when incorporated with a small amount of black carbon. A typical nickel-coated carbon fiber contains 2.75% of nickel—coated carbon fiber, which results in a substantial increase in shielding performance.
Stainless Steel Mesh
Stainless steel mesh for EMF shielding is a valuable material for various applications. Its uniform black coloration provides a practical shielding effect against electromagnetic waves. In addition, its high attenuation value makes it a good choice for communications and laboratory applications. The material is also suitable for use in warfare and battlefield tactic systems.
Stainless steel mesh is a lightweight, partially transparent, and corrosion-resistant material. Its tight-knit pattern ensures good shielding while maintaining airflow. As a result, it is a suitable choice for shielding sensitive areas and boxes. The material is also self-adhesive, making it an ideal choice for protecting electronic and other equipment.
