Nano-powder refers to powder whose particle size is between 1-100 nm. Nanoparticles have a small size effect, a large specific surface, and a macroscopic quantum tunneling effect, so nanopowders show many excellent properties that micron-scale powders do not.
Copper Nanoparticles Properties:
Copper nano powder, which is a purple-brown or purple-black powder, is used for the production of microelectronic devices and is used to manufacture the terminals of multilayer ceramic capacitors.
Nano-copper has superplastic elasticity, which can be elongated more than 50 times at room temperature without cracks. Researchers at the French National Research Center found that copper nanocrystals with an average volume of only 80 nanometers have amazing mechanical properties, not only three times the strength of ordinary copper, but also very uniform deformation without obvious regional narrowing.
It is the first time that scientists have observed such a perfect elastoplastic behavior of matter. The mechanical properties of copper nanocrystals have opened up bright prospects for the manufacture of elastic materials at room temperature.
Copper has excellent conductive properties. After being processed into the nanopowder, copper nano powder no longer have conductive properties, but with other superior performance, such as antibacterial, deodorant, catalysis, lubrication.
Copper nanopowder has a large specific surface and a large number of active surface centers. It is an excellent catalyst in the metallurgy and petrochemical industry. In the hydrogenation and dehydrogenation of high molecular polymers, the copper nano powder catalyst has extremely high activity and selectivity. In the process of acetylene polymerization to make conductive fibers, the copper nanopowder is a very effective catalyst.
In the process of automobile exhaust purification, copper nanopowder can be used as a catalyst to replace the precious metals platinum and ruthenium partially, convert toxic carbon monoxide into carbon dioxide, and convert nitric oxide into nitrogen dioxide. With the development of the electronics industry, the ultrafine thick film paste prepared from copper nanopowder will play an very important role in large-scale integrated circuits.
Nano Copper Powder Uses:
Copper nanopowder is used as a thermal hydrogen generator, gel fuel, active combustion agent, catalyst, water cleaning adsorbent, sintering active agent, antibacterial agent, etc.
Copper nano powder is easier to react with oxygen than ordinary copper.
The copper atoms in nano-copper are the same as those in ordinary copper, but the nano-copper particles are very small.
The chemical properties of nano-copper are more active than ordinary copper, and even change the inherent properties, but nanomaterials do not change the state of matter.
The sterilization mechanism of copper: Cu and water undergo a chemical reaction under aerobic conditions to produce hydroxyl radicals (-OH) and active oxygen ions (O2-). They have a strong redox effect and can destroy the proliferation of microorganism cells, Thereby inhibiting microorganisms. The specific surface area of nano-copper is increased, and chemical reactions are more likely to occur.
Copper is a heavy metal, and its bactericidal effect is also recognized (such as silver). Heavy metals are all toxic, and reaching a certain dose in the human body will have an impact on health and even pathogenic poisoning (silver also has certain neurotoxicity and genotoxicity). Copper is one of the essential trace elements of the human body and can be metabolized and absorbed by the human body. At the same time, silver is difficult to metabolize in the human body and will be enriched in the human body. Therefore, the use of nano-silver as an antibacterial agent has been banned in Europe and the United States, and some nano-copper has been used as an alternative.
1. Metal and non-metallic surface conductive coating treatment: Nano aluminum, copper, nickel powder has a highly activated surface, and the coating can be performed at a temperature lower than the melting point of the powder under oxygen-free conditions. This technology can be applied to the production of microelectronic devices;
2. Efficient catalyst. Copper and its alloy nanopowders are used as catalysts with high efficiency and strong selectivity, and can be used as catalysts in the reaction process of carbon dioxide and hydrogen to methanol;
3. Conductive paste. Using copper nanopowder instead of precious metal powder to prepare an electronic paste with superior performance can greatly reduce the cost. This technology can promote the further optimization of microelectronics processes;
4. Raw materials for bulk metal nanomaterials: using inert gas shielded powder metallurgy sintering to prepare bulk copper metal nanocomposite materials;
5. Drug additive materials: additive materials for the treatment of osteoporosis, bone hyperplasia, and other new special effects drugs;
6. Nano-metal self-healing agent: added to various mechanical equipment metal friction pair lubricating oil to achieve self-healing of the worn part of metal friction, energy-saving, and consumption reduction, improve equipment life, and maintenance cycle.
