      Scientists using carbon nanotubes(CNTs) and polymer film to develop new fabrics: can resist chemical and biological weapons       Scientists from Lawrence Livermore National Laboratory used carbon nanotubes and flexible polymer film to make synthesis of a breathable, lightweight fabric, wihch could help soldiers against the chemical and biological weapons.  A unique channel created by Carbon Nanotubes has achieved a good air permeability. Meanwhile, the density of the fabric, of which was only 5 nm pore diameter was quite high. It is understood that biological weaponsa such as viruses, usually it's bigger than 10 nm in size. In the experiment, the scientists confirmed that the new material is with the ability to repel dengue virus.  At the same time, to make the research results protects against chemical weapons also, scientists used some chemical-sensitive materials to improve carbon nanotubes, and ultimately achieved the goal.       Here sells purest and cheapest Carbon Nanotubes in the world. Carbon nanotubes is available with different purity grades and surface functionalization. Carbon Nanotubes is produced by Chemical Vapor Deposition (CVD) method by HW NANO and depending on the diameter one can obtain either single-walled Carbon Nanotubes(SWCNTs) ,double-walled carbon nanotubes (DWCNTs)or multi-walled Carbon Nanotubes (MWCNTs). Our current capacity for the production of MWCNTs far exceeds that of other suppliers.   Spec of carbon nanotubes:   1) SWCNT: diameter: 2nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%   2) DWCNT: diameter: 2-5nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%   3) MWCNT: diameter: 8-20nm,30-60nm,60-100nm, Length: short tube 1-2um and long tube 5-20um, purity: >99%   4) Low purity for the three ones above are all available.   5) Functionalized carbon nanotubes: COOH-CNTs, OH-CNTs, Amino-CNTs, Metal coated CNTs...   6) Dispersion: CNTs water dispersion, and CNTs oil dispersion.

Tin Oxide Nanoparticles for Conductive SnO2 ceramic       Ceramic is a good insulator and not conductive material in general. Ceramic is made from oxides mainly; the outer electrons of the atom usually is attracted to the nucleus and are bounded to the surrounding atoms of the atom, then the electrons are not free to move. That makes the general oxide ceramic not conductive. However, by using the Tin oxide nano powder as the main component and mix with Sb2O3, CuO, ZnO, PbO, Fe2O3 and other components to make the ceramic electrode material.     For SnO2 is the main component, adding Sb2O3, CuO, ZnO, PbO, Fe2O3 and other components of the electromagnetic flowmeter with ceramic electrode materials. The conductive ceramic is available to make in ordinary ceramic technology such as in the oxidizing atmosphere at 1300 ~ 1360 ℃ under firing. For the SnO2 conductive ceramic resist the erosion of various concentrations of strong acid, and with excellent conductivity in room temperature. If use of the SnO2 ceramic instead of the current platinum electrode, users could save a lot of platinum and greatly reduce costs. For the SnO2 ceramic is available to use as solar cell electrodes, and the general heating, corrosion-resistant heating and so on.     HW NANO SNO2 TIN OXIDE NANOPARTICLES, PARTICLE SIZE 20NM, 50NM, 80NM...PURITY 99.99%     Tin oxide nanoparticles has application in electronic devices. It is used in liquid crystal displays, optoelectronic devices, solar cells, gas sensors, and resistors. It is also used in anti-static coatings, and energy conserving coatings. It has applications in catalysis. It is used in transparent heating elements. By Lyla

      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.
