Nano Ag Silver powder cas 7440-22-4

About Nano Silver Ag powder:
Nanosilver is a new type of nanomaterial, with metallic silver as the main component, and its particle size is reduced to the nanometer level by a special preparation process. Its particle size is usually around 25 nanometers. First of all, nanosilver has strong antibacterial properties. Because its particle size is very small, smaller than the diameter of most bacteria, it can easily penetrate the bacterial cell wall and directly kill bacteria. Secondly, nano silver also has good electrical conductivity. Because of its tiny particle size and large specific surface area, it has a high conductivity, making it occupy an extremely important position in the field of microelectronics.

Applications of Silver nano powder:
Nanosilver particles (NSPs), are among the most attractive nanomaterials and have been widely used in a range of biomedical applications, including diagnosis, treatment, drug delivery, medical device coating, and personal health care.

1. Medical field:

Nanosilver has a wide range of applications in the medical field, the most representative of which are antibacterial dressings and antibacterial coatings. Nanosilver antibacterial dressings and antibacterial coatings can effectively inhibit and kill various pathogenic microorganisms, such as bacteria, fungi, etc., thereby preventing the spread of infection. Nanosilver can also make drug carriers deliver drugs directly to the lesion site, improve drug efficacy, and reduce drug side effects. In addition, nanosilver can also be used to make medical sensors, medical devices, and other fields. 

2. Textile field:

Nanosilver has good antibacterial, odor-proof, and mildew-proof properties, so it is widely used in the textile field. Nanosilver textiles can effectively prevent the growth of microorganisms such as bacteria and fungi to keep the textiles clean and hygienic. At the same time, nano silver textiles also have good breathability and comfort, which can meet people's pursuit of high-quality life. 

3. Microelectronics field:

Nanosilver has excellent electrical conductivity, which makes it one of the important materials in the field of microelectronics. Nanosilver can be used to make microelectronic devices, such as circuit boards, chips, etc., and can also be used to repair damaged circuit boards, replacing the traditional electroplating process. In addition, nanosilver can also be used to make electronic storage devices, such as flash memory, memory, and so on. 

4. Cosmetics field:

Nanosilver has good antioxidant and anti-inflammatory properties and is widely used in cosmetics. Nanosilver cosmetics can effectively be antioxidant and anti-inflammatory, reducing skin-free radical damage, thereby keeping the skin healthy and young. At the same time, nano silver cosmetics also have good permeability and absorption, can be quickly absorbed by the skin, and improve the efficacy of cosmetics. 

5. Other fields:

Nanosilver can also be used in the energy field, such as making solar cells, fuel cells, and so on. Nanosilver can also be applied in environmental governance, such as removing harmful substances from water and purifying air. In addition, nanosilver can be used in construction, such as producing paint, building materials, etc.

Production Method of Nano Silver :
There are many ways to produce nanosilver, including chemical reduction, electrochemical reduction, microemulsion, etc. The following are several common nanosilver production methods: 

1. Chemical reduction method:

Chemical reduction is among the most popular methods to make nanosilver. The method is to reduce silver ions to silver elemental by controlling the concentration of the reducing agent, reaction temperature, reaction time, and other conditions, and prepare it into nanometer particles. The method of chemical reduction has the benefits of cost-effectiveness and simple operation, but the size of silver nanoparticles produced is uneven and easy to oxidize. 

2. Electrochemical reduction method:

Electrochemical reduction is a method of reducing the surface of the electrode. The method reduces silver ions to silver elemental by applying a certain voltage on the electrode surface and preparing them into nanoscale particles. The electrochemical reduction method has the advantages of high production efficiency and uniform size of silver nanoparticles. Still, it needs to use a lot of electrolytes and has a high cost. 

3. Microemulsion method:

The microemulsion method is a method of preparing nanoparticles by microemulsion system. The method is to dissolve silver ions and reducing agents in a microemulsion system, reduce silver ions to silver elemental by controlling the size and stability of the microemulsion, and prepare them into nanoscale particles. The microemulsion method has the advantages of uniform size and controllable shape of silver nanoparticles, but it needs to use a lot of organic solvents and has high production costs. 

4. Biological reduction method:

Biological reduction is a method of using biological enzymes or microorganisms to reduce silver ions to silver elements. The method is to reduce silver ions to silver elemental by controlling the number of biological enzymes or microorganisms, reaction temperature, reaction time, and other conditions, and prepare it into nanoscale particles. The biological reduction method has the advantages of low cost and environmental protection. Still, the production efficiency is low, and it needs to use a lot of biological enzymes or microorganisms.

Storage Condition of Nano Ag Silver powder:
The damp reunion will affect Ag powder dispersion performance and using effects, therefore, silver Ag powder should be sealed in vacuum packing and stored in a cool and dry room, the silver Ag powder can not be exposure to air. In addition, the Ag powder should be avoided under stress.

Packing & Shipping of Nano Ag Silver powder:
We have many different kinds of packing which depend on the silver Ag powder quantity.
