      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.  

In high crystallinity matrix resin, adding materials with high thermal conductivity is the most effective method to improve plastic thermal conductivity.The thermal conductive filler is refined and even nano size is made, which not only has little effect on mechanical properties, but also improves thermal conductivity. With the addition of nanometer magnesium oxide Magnesia Nanoparticles of high purity, good whiteness, small particle size and uniform particle size, the thermal conductivity is made up of ordinary 33W/(m).K) raised above 36W/(m. K). It can be used in PA, PBT, PET, ABS, PP, organic silicone, coating and other materials to play the role of thermal conduction. Thermal conductive agent: this product has excellent thermal conductivity, suitable for thermal interface materials, such as thermal plastic, thermal resin castable, thermal silicone, thermal powder coating, functional thermal conductive paint and various functional polymer products. The thermal conductivity can reach 3.4w/m.k. when 80% high-purity nanometer magnesium oxide is added into PPS. When 70% aluminum trioxide is added, the thermal conductivity can reach 2.392W/m.K. Notice: Nano Materials have lots of applications that we canot list one by one. And the applications we listed is theorically available according to characteristics of certain Nano Material and researches. For practical applications we would strongly advise you to have sample for testing. Thanks. 

Nano Antimony Tin Oxide Particle/ATO Nanopowder can be sued as Catalyst Carrier/Support for it has good electrical conductivity, chemical stability and good mechanical attrition properties similar to metals and it helps improving catalytic performance for precious metals.
