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.

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.

The best dog ball EVER!!!
Our 3 y.o. Mini Australian shepherd destroys every toy that she can. We can’t have any kind of cloth toys, including the heavy duty, triple stitched, fire hose Kong toys. We can’t have rope toys, even the balls. There are many rubber or silicone toys we also can’t have as she destroys them as well. She has 5 of these balls, some for over a year and they are still in GREAT shape. Left in the sun, rain, etc, they just hold up. They also don’t have a lot of surface area to hold slobber so your hand doesn’t get all wet. Heavy enough to still throw a fair distance, but light enough that the dog was fine the few times I’ve accidentally drilled her in the ass. These are the best.

The best dog ball!
I have bought about 8 of these balls now. Mostly because my dog looses his or I’m buying them for my other dog friends. I put a dog bone in it at dinner time and it keeps my dog occupied while I’m eating my dinner. He loves it and so do I! They also have different sizes. We recently got a bigger dog breed so I got the biggest one. He loves it as well! Worth every penny!

Long term durability and still my dogs fav toy!
We’ve had this ball for 13 months now. It’s still my dogs #1 favorite toy. I have dogs like that to chew and they have tried but this thing is still fully intact. Definitely got my moneys worth and my dogs love it!!

Dog loves them
I have these balls in every size they come in. My dog loves them and they are the only thing that he can’t destroy. I also have put a squeaker from a destroyed toy inside of one (it was a difficult thing to do) and made my own indestructible squeaky ball as well as putting a small sized ball inside a medium sized ball to make something that he plays with on his own for hours. Even if you just use it as a ball without any of the modifications I have done I highly recommend this product. You can play with your dog indoors and not be too concerned about damaging anything. It also is great for playing in the snow since it doesn’t sink as far as other balls.

Great for small dogs
This ball lasted 5 minutes for my bully. That's my fault for not reading that it was small. I'm going to look for the largest size in hopes to get a few more minutes worth of chomps. My dog loved it.
