      Nano silver/polymer composite materials, as an important member of the composite materials, with its excellent physical and chemical properties, has got fast development in terms of effective antibacterial sterilization. Small particle size,large specific surface area and more surface activity center number, silver nanoparticles is playing an role of the high catalytic activity and selectivity, and polymer material can prevent reunion of silver nanoparticles and keep long-term stability.       Nano silver/polymer composite materials can become excellent antibacterial materials, the main reasons are as follows: 1. After the nano silver is composited to polymer,the material is more stable, silver ions loss is slower, duration is longer, bacteriostasis effect is more lasting. 2. The specific surface area of silver nanoparticles is big, and can touch the microbes to a greater availability,therefore, sterilization rate is higher. 3. Non-toxic to human body but can efficiently kill microorganisms, and won't become resistant. 4. Some of the polymer itself has antibacterial, after being composited synergies produces, bacteriostatic effect is better.       the polymer compositing nano silver should have the features in below: 1. Stable physical and chemical properties, can be used as a bearing base of silver nanoparticles. 2. Do not react with silver nanoparticles, nano silver antibacterial properties will not be lowered. 3. Some of the polymer itself has antibacterial property, which can enhance the bacteriostatic effect of material.       Polymers commonly used as composite include polyethylene oxide PEO,  polyaniline PAn, Polyrhodanine, cellulose,  polypyrrole PPy,  poly dopamine PDA and so on. These are the quite ideal composite materials with silver, can improve the effect of antibacterial material.       The polymer price is cheaper, has a wide source, so nano silver/polyer composite cost is reduced, and the bacteriostatic effect enhance, it will become an important trend of future research.       Based on the above reasons,in medicine, nano silver/polymer composite materials are used in a bandage, dentist, catheters, etc., in maritime, silver nanoparticles/polymer composite materials is used in ship manufacturing, in life, it is used in the water, clothing, baby supplies, and other fields.Predictably, the future life will be is closely related to nano silver/polymer composite materials.       Hongwu International Group Ltd is committed to provide high-quality silver nanoparticles with the most reasonable price for customers who are doing nanotech research and have formed a complete cycle of researching, manufacturing, marketing and after-sale servicing. The company’s silver nanoparticles have been sold to many countries around the world. if you have any request about silver particles, please feel free to contact us at hwnano@xuzhounano.com.

It is not only the lightest, but also the hardest ceramic material and has excellent thermal conductivity, low thermal expansion and is very resistant to acids and lyes. typical application for silicon carbide components is dynamic sealing technology using friction bearings and mechanical seals, for instance in pumps and drive systems. Compared to metals, silicon carbide enables highly economical solutions with longer tool life when used with aggressive, high-temperature media. Silicon carbide ceramics are also ideal for use in demanding conditions in ballistics, chemical production, energy technology,  paper manufacturing and as pipe system components.

Nano Silicon powders is non-toxic, odorless, and with active features. Nano silicon powder is a new material for high capacity lithium battery anodes. Silicon nanopowders use for the rechargeable lithium battery cathode material: Due to the high absorption rate of nanometer silicon and lithium batteries, the nano silicon for lithium can significantly increase the capacity of lithium battery (theory can reach 4000mA / h). Nano silicon powder and graphite replace the nano carbon powder as raw materials for the lithium anode material, use the mechanical milling method for preparing the best ratio of silicon / graphite composites, silicon and graphite, which is 1:9. Composition Si-C composite material, can effectively reduce the expansion when silicon absorption lithium ions, increase the affinity with the electrolytic solution, and easily dispersed and can improve the cycle performance. Nano silicon nanowires made of silicon powder used in rechargeable lithium battery anode material in or on the surface of the nano silicon powder coated graphite anode materials used in rechargeable lithium battery, rechargeable lithium batteries can be improved more than three times the capacity and charge-discharge cycles.
