      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.

High filling & low viscosity flake silver powders for epoxy resin conductive adhesive use       Conductive adhesive is a special kind of adhesion agent, mainly composed of resin and conductive fillers, such as silver powder, gold powder, copper powder, nickel powder, graphite powders, etc.), can be used as adhesive materials in microelectronics components, encapsulation manufacturing process.         Conductive adhesive with flake silver powder has excellent electrical conductivity, adhesion and chemical stability. Silver powder almost not be oxidized in the rubber, in air its oxidation speed is very slow, even if is oxidized, silver oxide generated still has good electrical conductivity. therefore, in the market, especially on the high reliability requirements of electric installation, flake silver powders as conductive filler is used mostly. And in the choice of matrix resin, epoxy resin is the best because of its high content of active group, high cohesive strength, good adhesion and excellent mechanical properties.       HW NANO flake silver powder, with particle size <1um, 1-3um,5-8um,10um, purity 99.99%. Specific surface area and apparent/bulk density are adjustable flexibly. It is available with small quantity for researchers and bulk order for industry groups.          Silver powder filling quantity influence on the properties of conductive silver glue. after silver powders as conductive filler is added to the epoxy adhesive, the conductive mechanism is the contact between of silver powders.After system curing, silver powders connect into chain circuit with each other, presents the conductivity. the data shows that the adding quantity of silver powder to 80% or so, the conductivity is the best.
