Name: High Quality carbon nanotube 18-40nm

Product Overview

Multi-walled carbon nanotubes (MWCNTs) are important nanomaterials with unique structures and excellent properties. Multi-walled carbon nanotubes are hollow tubules composed of multiple coaxial graphite cylindrical surfaces, and the spacing between adjacent cylindrical surfaces is comparable to the spacing of graphite layers. Multi-walled carbon nanotubes can be seen as coaxially nested with multiple single-walled carbon nanotubes of different diameters, with the number of layers ranging from 2 to 50, and the spacing between each layer is consistent, forming a cable-like multilayer structure. At present, the preparation methods of multi-walled carbon nanotubes mainly include arc discharge method, laser ablation method, chemical vapor deposition (CVD) method and flame method. Among them, the chemical vapor deposition method is widely used because of its simple equipment and high product purity.

Technical Parameter

Product Features

Excellent mechanical properties: with extremely high strength and toughness. Its theoretical strength can reach tens or even hundreds of times that of steel.

Excellent electrical performance: can exhibit good conductivity, depending on aspect ratio, structure, and preparation method.

Good thermal performance: high thermal conductivity, capable of effectively transferring heat.

Large specific surface area: This makes it potentially applicable in fields such as adsorption and catalysis.

Application Fields

Additives in polymers, catalysts, electron field emitters for cathode ray lighting components, gas discharge tubes in telecommunications networks, energy conversion, lithium battery anodes, hydrogen storage, nanotube composite materials (by filling or coating); Sensors, reinforcement in composite materials, supercapacitors, etc.

Comfortable Socks, color variety not as implied
Size: Medium, Color: True Gray Heather Assorted (6 Pairs)
Pros: Comfortable socks, with wide, not tight band at the ankle. Wish I'd bought them sooner. Con: Amazon description shows a photo of 6 pairs of socks, 2 black, 2 gray, and 2 white. The pack actually comes with 2 black, 1 white, and 3 pairs of gray. Haven't washed them yet. Will see how they stand up.

Not polyester! Thank you UA!
I never realized shopping for cotton socks in 2024 would be so difficult. Luckily I found these, and all the other Under Armour cotton socks and they are the best. I cannot wear polyester, and these only have like 1%. I didn't realize our cotton is being replaced by polyester, and I don't like it. Bath towels don't work anymore either... I need my cotton socks and towels, I love incandescent light bulbs, I'll always have a gas powered mower and leaf blower. Also butterfinger should've never their recipe. Just sayin...

Great sock for everyday
Size: Large, Color: Black/Gray (6 Pairs)
So these are awesome but they are slightly thinner than older versions, shorter too. Just FYI if you a long time UA customer. If you have never had their socks, I love them personally and only like one other brand better. They aren’t overly thick and they allow your feet to breath. I never have sweaty feet in these even in my warm boots. I also like that they don’t cut into my feet or get holes in the toes over long terms. The only reason I’ve thrown these out has been fraying near the ankle or someone (kids) thieving them.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!
