Application prospects of nano silver materials

Due to its special microstructure, nanomaterials have the characteristics of small size effect, surface effect and macroscopic quantum tunneling effect. Silver element is a kind of precious metal. The physical and chemical properties of bulk materials are stable and have good antibacterial and biocompatibility. Nano-silver materials have excellent catalytic properties while having these properties, and their applications include biology, medicine, environmental protection, and the electronics industry.

1 Applications in the medical field
Silver can degrade bacterial proteins and has the characteristics of broad-spectrum sterilization. Since the nano silver particles have a small particle size and a large specific surface area, their bactericidal properties are significantly enhanced compared to bulk silver materials. For common harmful bacteria, such as Staphylococcus epidermidis and Escherichia coli, the non-woven fabric is impregnated with nano-silver solution to obtain good antibacterial properties. In addition to effectively killing and inhibiting bacteria, nano-silver particles also have certain inhibitory effects on fungi, viruses, cancer cells, etc. These effective effects make nano-silver particles have broad market prospects in the medical and health fields.

2 Applications in the field of catalysis
Since the nano silver particles have the characteristics of small particle size, large specific surface area, and many dangling bonds, they exhibit good catalytic activity and can be used as catalysts for various reactions. Studies have shown that nano-silver particles can significantly increase the reaction yield, shorten the reaction time and the purity of the reaction products in the polycondensation reaction of the synthetic osmium iridium oxide derivatives compared with other nanomaterial catalysts. In the field of biocatalysis, nano silver particles interact with amino groups in amino acids contained in proteins, and the intervention of silver enhances the catalytic activity of the enzyme.

3 Applications in the electronics industry
In the field of electronics industry, silver paste has an irreplaceable function in the process of using simple process and stable performance. At present, the well-developed conductive silver paste is mainly conductive through silver powder of micron or submicron scale. With the rapid development of new technologies such as low temperature sintering and multilayer wiring in the electronics industry, the performance of these pastes cannot meet the requirements, so the materials are The structure and performance of its own put forward higher requirements. When the conductive silver paste is filled with silver particles having a particle size of nanometer order, the melting point is lowered, the surface activity is increased, the specific surface area is increased, and the thermal conductivity is increased due to the size effect. These physical properties make it satisfy high power, The heat dissipation requirements of high-density systems are suitable for multi-level packaging.
