Product Overview

Carbon nanotubes are simple substances composed of carbon atoms, which can be regarded as hollow tubular structures formed by the curling of graphene. On the surface of carbon nanotubes, carbon atoms form bonds with each other in the form of sp2 hybridized orbitals, arranged in a regular hexagonal graphite layer structure. In theory, this hexagonal structure is perfectly and uniformly distributed on the surface of the entire carbon nanotube. In terms of topology, the shared structure and properties between graphene and carbon nanotubes are one of the important factors contributing to their similar properties. However, due to the curvature of the graphite layer in carbon nanotubes and the potential defects that may occur during the growth process, sp3 hybridization may occur in the hexagonal ring structure on the surface of carbon nanotubes, leading to the formation of pentagonal or seven membered rings. Carbon nanotubes are classified into single-walled carbon nanotubes, double walled carbon nanotubes, and multi walled carbon nanotubes based on the curling of graphite sheets with different layers.

There are many preparation processes and methods for carbon nanotubes, and carbon nanotubes with corresponding properties and structures can be prepared through different methods. At present, the main methods for preparing carbon nanotubes include graphite arc method, laser evaporation graphite method, and chemical deposition method. Chemical deposition method has the advantage of large-scale production and is currently a widely used method.

Product Features

Multi walled carbon nanotubes have many unique properties:

Excellent mechanical properties: with extremely high strength and toughness. For example, 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

1. Composite material reinforcement: Multi walled carbon nanotubes have high strength and toughness. Adding them to matrices such as plastics, rubber, and metals can significantly improve the mechanical properties of the material, such as strength and stiffness. For example, grafting carbon nanotubes onto the surface of carbon fibers to obtain a multi-level structure can enhance the interfacial interaction with organic matrices and the mechanical properties of composite materials.

2. Electronic devices: Although their conductivity is not as single and excellent as single-walled carbon nanotubes, they still have good conductivity and can be used to manufacture high-performance conductive inks, sensors, flexible displays, and other electronic devices.

3. Electrode materials: Can be used as electrode materials for lithium-ion batteries and supercapacitors to improve energy storage and power output capabilities.

4. Catalysts and catalyst carriers: They can serve as catalysts themselves. It can also serve as a catalyst carrier, providing more active sites for catalytic reactions and enhancing catalytic performance due to its large specific surface area and unique structure. For example, acidified multi walled carbon nanotubes can be used as carriers to load composite inorganic salts, resulting in solid acid catalysts with superior catalytic effects than single component iron sulfate.

5. Energy field: In addition to the applications mentioned earlier in batteries, it can also be applied to hydrogen storage materials. The unique hollow structure and nanometer diameter of carbon nanotubes provide favorable conditions for hydrogen storage.

6. Absorbing materials: They have a certain ability to absorb electromagnetic waves and can be used to prepare absorbing materials. They have potential applications in military stealth, electromagnetic shielding, and other fields.

7. In the field of biomedicine: Its unique hollow structure and nanometer diameter can provide space for accommodating drugs, achieve high drug loading, and can pass through cell membranes and various biological barriers to deliver drugs to the inside of cells. In addition, it can effectively reduce the release rate of drugs and improve the sustained release effect.

Great chew toy
Size: 10.5 inch Rubber Flex Tread
This is my second time buying the Tonka rings. My dog loves this chew toy. It does take him a bit to destroy them. I give this toy to him as a reward otherwise it be destroyed in 3 days. I have a pitty. So other dogs it should last longer. They are shin whackers and hurt when they connect. So I make sure to watch the dog and toy around small kids and elderly to be safe. They are heavy and made well.

Finally a toy we can leave out!
Size: 10.5 inch Rubber Flex Tread, Size: 10.5 inch Rubber Flex Tread
There are very few toys that we can leave out for our 11 month old golden. Which is a shame because as a small puppy, we taught him to bring us a toy to initiate play instead of nipping. Ropes or stuffies never lasted more than a few minutes so they always had to be taken away. One time he brought us a benenbone to play tug. So I tried this as a last resort. Finally something we can keep out for him! It’s not completely indestructible. He has figured out how to pull bits of tread off. But he chewed hard on it for a solid 20 minutes and it’s still intact with the exception of a few small tread pieces. Can’t say that for 99% of the other dog toys on the market! UPDATE: OK, so it's definitely not indestructible. After a few days of dedicated gnawing, he has almost chewed through the yellow ring so we can't leave him too unsupervised with it. I'm still going to leave it as 5 stars since it's the best tug toy that I have found so far and we have tried a lot! I may buy another one and just make sure I don't let him freely chew on it for any length of time.

Really wanted this toy to be better...
Size: 10.5 inch Rubber Flex Tread
I got this toy because I have 3 large dogs that all like to pull things. I can't always play with them even though they follow me everywhere wanting to play, so I saw this toy and thought it would be good because it would give them something they can tug away at with each other. I saw the thick rubber and thought it would last awhile, but I was wrong. My German Shepherd and Pyrenees mix chewed though the first tire rather quick, and before I realized, I was finding chunks of tire around the house and yard. Thankfully, none of them tried to eat it. It seems like it could be a good toy for an aggressive chewer IF they are smaller and not as strong as these large dogs are, but it did not hold up long to mine.

My dog's favorite toy* (*see durability warnings*)
Style: Variety Pack - Large (3-pack)
This is a plush toy, so *if your dog is a destroyer of things, it'll destroy this toy easily/instantly* & if they're not destroyed right away, I'd definitely expect them to be destroyed eventually just given the type of toy it is- plus much of that depends on the way your dog plays. That said, this plush, multiple squeaker toy has held up really well for the amount of use it gets in our home. Because it contains 3 separate squeakers in it, these toys have been like heaven for my 3 year old, male, Toy Fox Terrier to play with- he freaks out when we squeeze more than 1 squeaker at the same time & I don't do all 3 at once bc I think his head might actually explode LoL 😋! Seriously, ever since he's grown out of puppy-hood, he's much less destructive with his toys now, so we are able to buy toys like these for him, have him go nuts freaking out on them & have them hold up pretty well/for a while before it's time for a replacement, yet since they're not very expensive, it's not terribly hard to replace them if needed (he's still using the last toy in the original 3 pack we got for him). It's great for fetching via a "flinging" motion (they're not heavy enough to actually throw) if you have a smaller dog who doesn't cover much distance too readily, but the best part of this toy is the elongated design of it, because it makes for a perfect "tug of war" type of playtime toy with my little buddy (tugging is a behavior which you may or may not want to encourage your dog to do depending on its disposition). Since my dog thankfully isn't really destructive & doesn't have issues releasing a toy from a tugging interaction anymore, these items have held up pretty well for a plush type toy, but again, if you own a dog known for destroying their toys, or anything else for that matter, these probably aren't going to work out well for you. Given they're pretty cheap to replace, for a throw ready, tug toy which has 3 different places for a dog to chomp on to make it squeak, they've turned out to be perfect for our smaller sized pup & have become a favorite toy of my little guy which he's always ready to play with, at any time, with anyone- he's got it ready to go a lot of the time when we get back home to him after being out. Again, you'll need to go with Kong or something similarly durable if your dog destroys things or is still a puppy who doesn't know better, but for an average amount of wear & tear they've held up really well while remaining at the top of my dog's favorite toy list. So recommended for sure, but just know if you've got a chewy character on your hands, despite all the fun they'd have with these, I'd get a more durable toy instead of this one as these plush toys, while good quality, will not hold up to prolonged abuse (as is the case with most plush toys sold). However, for an "average destruction" level dog, it seems well enough made to last a decent amount of time & they're a source of an enjoyable playtime for our dog & therefore for us as his owners as well! Definitely recommend for it's features, like 3 different squeakers, it's great design for a tugging style of play & it's overall good durability for a plush style toy. 👍
