Powders with particle sizes between 1-10 nm and 100-100 nm are called nanopowder. These nanoparticles are able to exhibit many superior properties than other micron-scale particles, including a microscopic quantum tunneling, small size effects, and large specific surfaces.
Copper Nanoparticles Properties:
A copper nano-powder, also known as purple-brown and purple-black, is used to create microelectronic devices.
It has superplastic flexibility, and can be extended at room temperatures more than 50x without cracks. French National Research Center scientists discovered remarkable mechanical properties of copper nanocrystals. The average copper volume is only 80 nanometers. This means that they not only possess three times as strong as regular copper, but have uniform deformation, without any obvious narrowing.
For the first time, scientists have ever observed such an amazing elastoplastic behavior in matter. Bright prospects have emerged for the production of elastic materials at low temperatures thanks to the copper nanocrystals’ mechanical properties.
Copper’s excellent conductive abilities are evident. When copper nano powder was made from it, it no longer has conductive properties but instead offers superior performance in other areas, including antibacterial, deodorant catalysis, and lubrication.
Copper nanopowder exhibits large specific surfaces and numerous active surface centres. It works well in both the metallurgy industry and the petroleum sector as an effective catalyst. This copper nano powder catalyst exhibits high selectivity as well as high activity during the dehydrogenation and hydrogenation process of high molecularity polymers. It is an extremely effective catalyst when acetylene monomerization takes place to make conductive fibrils.
Copper nanopowder can also be used for exhaust purification. In large-scale integrated circuits, ultrafine thick film paste of copper nanopowder will become a key component due to its importance in electronics development.
Nano Copper Powder Uses:
Copper nanopowder serves many purposes, such as: catalyst, fuel, active, and thermal hydrogen generation, active, combustion, and sintering, active, and antibacterial agents, among others.
A copper nano powder reacts with oxygen more easily than the regular version.
The nano-copper copper atoms are exactly the same as ordinary copper. But the nanocopper particles can be very tiny.
Nano-copper is more active chemically than other copper. It can change some of its inherent properties.
The sterilization mechanism for copper is: Under aerobic conditions Cu and Water undergo a chemical process to form hydroxyl and active oxygen units (O2-) respectively. They can be used to kill microorganism cells and exert a strong redox action. This increases the surface area of nanocopper, which makes chemical reactions more likely.
Copper is one of the heavy metals. Silver and silver also have bactericidal qualities. Toxic heavy metals have adverse effects on the human health. Even if a small amount is consumed, it can lead to pathogenic poisoning and neurotoxicity. Copper is an important trace element of our body. It can be metabolized in the body and absorbed into the bloodstream. It is however difficult for silver to be metabolized in the human organism and will therefore be enhanced in the human system. The United States has banned the use of antibacterial agents made from nano-silver in Europe and America. A substitute has been found, which is nano-copper.
1. Both metal and nonmetallic surface-conductive coating treatment. Nickel powder, nano copper, and silver have a highly activated coating surface. This coating can be applied at a lower temperature than its melting point, under oxygen-free circumstances. This technology can be used in the production of microelectronics.
2. Efficient catalyst. It can be used to catalyze the reactions of carbon dioxide, hydrogen to methanol with copper and its alloy nanopowders.
3. Conductive paste. It is possible to reduce cost by substituting precious metal powder with copper nanopowder for electronic pastes that have superior performance. This technology allows for the optimization of microelectronics.
4. Use inert-gas shielded pulse metallurgy to produce bulk copper and metal nanocomposite raw materials
5. Drug additive materials are additive materials used in the treatment and prevention of osteoporosis, hyperplasia, or other conditions.
6. Use nano-metal self healing agents in various machinery metal friction pair oils for self-healing.
