How to improve the waterproof and moisture-proof performance of NFC anti metal absorbing materials?

NFC technology relies on short-range high-frequency radio waves for data exchange. However, in practical applications, the presence of metal objects can cause signal attenuation or distortion, thereby affecting communication quality. In order to overcome this challenge, NFC anti metal absorbing materials have emerged. This type of material not only absorbs electromagnetic waves to reduce reflection interference, but also must have good physical and chemical stability, especially in humid or watery environments. Therefore, researching and developing materials with excellent waterproof and moisture-proof propertiesNFC anti metal absorbing materialIt has become an important topic.

Methods to improve waterproof and moisture-proof performance

Material selection and formula optimization

Selection of Polymer Matrix

Choosing a suitable polymer matrix is the foundation for ensuring that NFC anti metal absorbing materials have good waterproof and moisture-proof properties. Common polymer materials such as polyurethane (PU), epoxy resin (EP), and acrylic all have certain waterproof properties, but their sensitivity to moisture varies. For example:

• Polyurethane: It has excellent elasticity and wear resistance, while providing good waterproof effect;

• Epoxy resin: After curing, it forms a dense cross-linked network that can effectively prevent water infiltration;

• Acrylic ester: has fast drying and good adhesion, suitable for various substrates.

According to the specific application requirements, the most suitable polymer matrix can be selected, and its waterproof and moisture-proof properties can be further enhanced by adding functional additives.

Optimization of absorbing fillers

In addition to the polymer matrix, the selection of absorbing fillers is also crucial. The ideal absorbing filler should not only ensure efficient electromagnetic wave absorption capacity, but also maintain the overall waterproof and moisture-proof performance of the material. Commonly used absorbing fillers include ferrite, carbon nanotubes, graphene, etc. These materials can improve their dispersibility and interfacial compatibility by adjusting particle size, morphological structure, and surface modification, thereby enhancing the overall performance of the composite system.

Structural Design and Processing Technology

Multi layer composite structure

The use of multi-layer composite structures can significantly improveNFC anti metal absorbing materialWaterproof and moisture-proof performance. For example, adding a waterproof breathable film or coating a hydrophobic coating outside the absorbing layer can block external moisture from entering without affecting internal gas exchange. In addition, the synergistic effect between different materials can be utilized to construct a more robust and durable protective barrier.

Surface treatment technology

Surface treatment technology is one of the effective ways to improve the waterproof and moisture-proof performance of NFC anti metal absorbing materials. Common methods include but are not limited to:

• Fluoride coating: endows the material surface with superhydrophobic properties, making it difficult for water droplets to adhere;

• Silane coupling agent modification: enhances the bonding force between the matrix and the filler, while providing additional waterproof protection;

• Plasma treatment: Changing the microstructure of the material surface to increase hydrophobicity and durability.

Environmental testing and validation

To ensure the development ofNFC anti metal absorbing materialTo maintain stable waterproof and moisture-proof performance under actual usage conditions for a long time, comprehensive environmental testing must be conducted. This includes but is not limited to:

• Accelerated aging test: Simulate temperature and humidity changes in natural environments to evaluate the aging rate of materials;

• Immersion experiment: testing the performance changes of materials in a fully immersed state;

• Salt spray corrosion test: to investigate whether the material will corrode or experience performance degradation in salt containing air.

Through rigorous testing and validation, reliable guarantees can be provided for product performance and guide subsequent research and development improvement work.
