Description:
Main applications of nano Ag powder:
1. Antibacterial: test report on Ag dispersion is available
The antibacterial mechanism of nano silver powder generally has the following aspects:
1.1. The surface catalysis of silver nanopowders affects the normal metabolism and reproduction of bacteria, resulting in death of bacteria.
1.2. The effective ingredients in antibacterial fibers act on cell membrane proteins. It can directly destroy the bacterial cell membrane and cause the cell contents to ooze out. Nano Ag is adsorbed on the cell membrane, which prevents bacteria and other microorganisms from absorbing amino acids, uracil and other nutrients necessary for growth, thereby inhibiting their growth.
1.3. The far infrared rays emitted from the surface of the antibacterial fabric with Ag nanoparticle have a certain wavelength range, which can inhibit the activity of bacteria and cause the death of them.
2. Catalyst: silver nano particles can greatly improve the speed and efficiency of chemical reaction.
3. High-end paste: composite conductive paste, conductive ink, new nano bonding materials nano silver paste, etc..
Some ideas on how to make nano Ag dispersion:
Regarding the dispersion of nano silver powder, it is usually recommended to add a suitable surfactant combined with a mechanical dispersion methods to achieve a good dispersion. A supersonic jet mill can be used to depolymerize and surface-modify the dried silver powder. The most commonly used surface modification include: PVP, oleic acid coated silver nano powder, etc.
Storage Condition:
Silver nanoparticle should be stored in a cool and dry place.
