Evaluation of Electromagnetic Shielding Effect of Conductive Non woven Fabric in Electronic Products

With the increasing popularity and complexity of electronic products, electromagnetic interference (EMI) issues are becoming increasingly prominent. Conductive non-woven fabric as a new typeelectromagnetic shielding materialDue to its excellent conductivity, flexibility, and processability, it has been widely used in electronic products. This article will evaluate the electromagnetic shielding effect of conductive non-woven fabric in electronic products, and specifically mention the product produced by Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand conductive non-woven fabric.

Electromagnetic shielding principle

Electromagnetic shielding mainly reduces the transmission of electromagnetic waves through the reflection, absorption, and internal dissipation of materials. Conductive non-woven fabric contains conductive fibers or coatings inside, which can effectively guide electromagnetic waves to propagate along the surface of the material, and convert electromagnetic wave energy into thermal energy through Ohmic loss, thereby achieving electromagnetic shielding.

Performance characteristics of conductive non-woven fabric

Conductive non-woven fabric combines the flexibility of non-woven fabric with the shielding performance of conductive materials, and has the following characteristics:

1. Good conductivity: Conductive fibers or coatings endow non-woven fabrics with excellent conductivity, enabling them to effectively shield electromagnetic waves.
2. Excellent flexibility: The flexibility of non-woven fabric substrate enables conductive non-woven fabric to adapt to various complex shapes and structures, making it easy to process and use.
3. Lightweight and High Strength: Compared to TraditionalMetal shielding materialConductive non-woven fabric has lighter weight and higher strength, which is beneficial for reducing the weight of electronic products and improving portability.
