DWCNT, short for Double Walled Carbon Nanotubes, have short tube 1-2um and long tube 5-20um, with diameter 2-5nm. DWCNTs also have good properties of electromagnetism, adsorption, catalytic, mechanical, etc.. And they're used in various fields. DWCNTs Dispersion and functionalized types can be customized.

Double walled carbon nanotubes(DWCNT) is widely used as gas sensor for its good properties to achieve high sensitivity and selectivity.

MWCNTs Multi-Walled Carbon Nanotubes Price have excellent electric conductivity and mechanical strength

DWCNTs Double-walled Carbon Nanotubes have excellent field emission performance, light in weight.

HONGWU Carbon nanotubes includes SWCNT,DWCNT,MWCNT,The composite of carbon nanotubes with fiber materials can significantly improve the strength and properties of the materials. Due to the excellent mechanical properties and high electrical conductivity of carbon nanotubes, their introduction into high-strength fibers can effectively enhance the tensile strength and stiffness of the fibers.

Dwcnts, 2-5nm diameter, 1-2um or 5-20um length, widely used in semiconductor films.

Nano Copper Oxide Powder insoluble in water, alcohol, ammonia solution dissolve slowly, soluble in dilute acid.

Hongwu Nano supplys barium titanate(BaTiO3) nanopowders with cubic, tetragonal phase, 50nm, 100nm, 300-400nm with 99.9%. Nano BaTiO3 powder is mostly used for electronic ceramic materials.

Nano ATO dispersion, could do the particle size at <10nm, 20-40nm, <100nm, 99.9% purity, could do it according to your required concentration.

Nano ceria, also called cerium dioxide/CeO2/ceric oxide, is an inorganic compound that exists in the form of fine particles with dimensions typically ranging from 1 to 100 nanometers. Nano CeO2 exhibits unique physical, chemical, and optical properties due to its nanoscale size, which differ significantly from those of bulk cerium dioxide. Hongwu Nano produces CeO2 with the size of <20nm and 30-60nm.

Silicon nanopowders sepcification: 30-50nm 99%+, brown yellow, good spherical 100-200nm 99.9%+,brown black, irregular crystal form 300-500nm 99.9%+,brown black, irregular crystal form 1-2um 99.9+%, dark brown, irregular crystal form Silicon nanopowder properties: High purity, good dispersion performance, small size, uniform distribution, large surface area, high surface activity, low apparent density. 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.
