Some nanomaterials for Thermochromic Application Some nanomaterials for Thermochromic Application

Thermochromism refers to the phenomenon where a material undergoes color changes under temperature changes. This change is usually caused by changes in the electronic or molecular structure of the material. Its application principle mainly involves t...

DWCNTs Double Walled Carbon Nanotubes

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.

                                            DWCNTs Double Walled Carbon Nanotubes Used as Bulb

 

1. C921-S, 2-5nm, short tube 1-2um, >91% purity

2. C921-L, 2-5nm, long tube 5-20um, >91% purity


Double Walled Carbon Nanotubes Used in Bulb:


1. Double-walled carbon nanotubes as filament tomake carbon nanotubes bulb. The results show that, at room temperature resistance of 9 Ω double-walled carbon nanotubes emitting a lower threshold voltagethan the general safety bulb (36 V, 40 W) in tungsten light bulb filament;under the same power, the illumination power is higher than tungsten wire bulb.

2. In the double-walled carbon nanotubes in the radiation spectrum at a wavelengthof 407 nm, 417 nm and 655 nm emission, etc. have significant peaks, indicatingthe behavior of the double-walled carbon nanotube has a coldelectroluminescence characteristics, i.e.. The study found double-walledcarbon nanotubes emitting bulb is emitting heat and cold comprehensive, andtherefore has a higher luminous efficiency than incandescent light andsignificant energy savings and good color rendering. 

3. In addition, the lightbulbs emit of carbon nanotube on the human eye are very friendly and isexpected to become the next generation of light sources. At lower vacuum, when double-walled carbon nanotubes electrically heated to above 2200 and after a period of time, due to the local temperature, partial double-walledcarbon nanotube bundles occurred integrated into a diameter of 5 ~ 10 nmsingle-walled carbon nanotubes it is possible to obtain a new method forlarge-diameter single-wall carbon nanotubes
