Silver Ag Nanopowder Water Dispersion (Ag, 2 nm, 200ppm)

Silver (Ag) Nanopowder Water Dispersion (Ag, 2 nm, 200ppm) is a water-based dispersion that contains silver (Ag) nanoparticles with a very fine particle size of 2 nm and a concentration of 200 parts per million (ppm). Here are the key technical specifications and properties of this material:

1. Composition and Properties:

• Material: The dispersion contains silver nanoparticles (Ag), known for their excellent electrical conductivity, thermal conductivity, and antimicrobial properties.
• Particle Size: The nanoparticles are extremely small, with a particle size of 2 nm. This is a very fine size, offering a high surface area relative to volume, which enhances the material’s reactivity and functional properties.
• Concentration: The 200 ppm concentration means that for every million parts of the dispersion, 200 parts are silver nanoparticles. This is a low concentration, suitable for specific applications where silver is required in small amounts.
• Water-Based: The nanoparticles are dispersed in water, making this material easy to handle and environmentally friendly, especially compared to solvent-based dispersions.

2. Key Features:

• Ultrafine Particle Size: The 2 nm particle size allows for superior reactivity and increased surface area compared to larger particles. This is important for applications that require enhanced catalytic or antimicrobial activity.
• Low Concentration: The 200 ppm concentration of silver allows for the precise use of silver without wasting material. This is useful in applications where silver needs to be added in controlled amounts, such as in coatings or electronic components.
• Water-Based Dispersion: Being a water-based dispersion, it is safer to use compared to solvent-based dispersions and can be handled without the need for specialized solvents or equipment.

3. Applications:

• Electronics and Conductive Inks: Due to its high electrical conductivity, silver nanoparticles are often used in electronic components, conductive inks, and past es for printed electronics and 3D printing.
• Antimicrobial Coatings: Silver nanoparticles are widely known for their antibacterial and antiviral properties. The 2 nm size enhances these properties, making this dispersion ideal for use in antimicrobial coatings, medical devices, and textiles.
• Catalysis: Silver nanoparticles have applications in catalysis for chemical reactions. The high surface area of the 2 nm particles makes them ideal for use in catalytic processes.
• Sensors and Biosensors: Silver nanoparticles are used in the development of sensors and biosensors due to their high sensitivity and ability to interact with biological molecules.
• Photovoltaic and Optoelectronic Devices: The 2 nm particle size of silver nanoparticles can also be useful in the development of optical and electronic devices, such as photovoltaic cells and light-emitting diodes (LEDs).
• Water Purification: Silver’s antimicrobial properties make it useful in water purification systems, where the dispersion can be used to inhibit microbial growth in water treatment applications.

4. Advantages:

• High Reactivity: The 2 nm particle size provides a very high surface area, which increases the material’s reactivity in catalytic and antimicrobial applications.
• Antimicrobial Properties: Silver nanoparticles are widely known for their antibacterial and antiviral properties, which can be leveraged in medical and consumer products.
• Environmental and Safety Considerations: The water-based dispersion makes it easier and safer to handle compared to solvent-based systems, reducing the environmental impact.

5. Handling and Storage:

• Storage: The dispersion should be stored in a sealed container in a cool, dry place to avoid evaporation of the water and prevent the nanoparticles from settling.
• Handling: Handle the dispersion carefully, wearing appropriate protective gear such as gloves and goggles, especially when dealing with nanoparticles, which can be hazardous if inhaled or ingested.
• Stirring: Regular stirring may be required to prevent sedimentation of the nanoparticles over time.

6. Potential Limitations:

• Sedimentation: As with most nanopowder dispersions, there may be sedimentation of the particles over time, which can affect the uniformity of the dispersion. Regular stirring is recommended.
• Limited Concentration: With a 200 ppm concentration, this dispersion may not be suitable for applications that require high amounts of silver for conductivity or antimicrobial purposes.

Summary:

Silver Nanopowder Water Dispersion (Ag, 2 nm, 200ppm) is a water-based dispersion containing silver nanoparticles with a particle size of 2 nm and a concentration of 200 ppm. Its high surface area, antimicrobial properties, and electrical conductivity make it ideal for use in antimicrobial coatings, catalysis, electronic components, and biosensors. The water-based formulation ensures ease of handling and safety, while the small particle size enhances the material’s reactivity for advanced applications.
