Product Overview

Carbon nanotubes are simple substances composed of carbon atoms and can be regarded as hollow tubular structures formed by the curling of graphene. On the surface of carbon nanotubes, the carbon atoms are bonded to each other in the form of sp2 hybrid orbitals, which are arranged as hexagonal graphite layers. In theory, this regular hexagonal structure is perfectly evenly distributed over the entire surface of the carbon nanotubes. Topologically, the common structure and properties of graphene and carbon nanotubes are one of the important factors for their similarity. However, due to the curvature of the graphite layer in the carbon nanotubes, coupled with the defects that may occur during the growth process, the sp3 hybrid phenomenon may occur in the six-membered ring structure on the surface of the carbon nanotubes, resulting in the emergence of five-membered rings or seven-membered rings. Carbon nanotubes can be divided into single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes according to the graphite sheets with different number of layers.

Product Features

 

Multi-walled carbon nanotubes have many unique properties:

Excellent mechanical properties: very high strength and toughness. For example, its theoretical strength can reach tens or even hundreds of times that of steel.

Excellent electrical properties: Can show good electrical conductivity, depending on length-diameter ratio, structure and preparation method.

Good thermal performance: high thermal conductivity, can effectively transfer heat.

Large specific surface area: This makes it a potential application in adsorption, catalysis and other fields.


Application Fields

 

1. Composite material strengthening: multi-wall carbon nanotubes have high strength and toughness, adding them to plastics, rubber, metal and other substrates can significantly improve the mechanical properties of the material, such as strength, stiffness and so on. For example, the multistage structure obtained by grafting carbon nanotubes on the surface of carbon fiber can enhance the interfacial interaction with organic matrix and the mechanical properties of composite materials.

2. Electronic devices: Although its electrical conductivity is not as single and excellent as that of single-wall carbon nanotubes, it still has good electrical conductivity and can be used to manufacture high-performance conductive inks, sensors, flexible displays and other electronic devices.

3. Electrode material: It can be used as electrode material for lithium-ion batteries and supercapacitors to improve energy storage and power output.

4. Catalyst and catalyst carrier: itself can be used as catalyst. It can also act as a catalyst carrier, and because of its large specific surface area and special structure, it can provide more active sites for catalytic reactions and improve catalytic performance. For example, acidified multi-walled carbon nanotubes can be used as a carrier to support composite inorganic salts, and the solid acid catalyst produced has better catalytic effect than single-component iron sulfate.

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

6. Wave absorbing material: It has a certain absorption capacity for electromagnetic waves, and can be used to prepare wave absorbing materials, which has potential application value in military stealth and electromagnetic shielding.

7. Biomedicine field: Its unique hollow structure and nanotube diameter can provide space for containing drugs, can achieve a high drug load, and can pass through cell membranes and a variety of biological barriers to deliver drugs to the interior of cells. In addition, it can effectively reduce the drug release rate and improve the sustained release effect.

8. Scientific research: It is often used in various scientific research to help researchers explore the properties and potential applications of nanomaterials.

Waste of Money
Color: Orange
Cool toy but my dog ate through it the second day he played with it. It is not for strong dogs. No durability. I had to throw away the orange covers and now he just throws it around.

Cool toy. Fun for all
Color: Blue
A cool toy. entertainment for the dogs but more so for the dog parents to watch the dogs reaction. Comes with an additional rope just in case, which I loved. Only side note I would say is that the fast mood could be a little faster. My Golden retriever figured out the speed in less than 24 hours and now picks up the toy to try to chew it up, instead of chasing. With him attempting to chew on the toy in the small time I give him, there are no teeth marks yet…this toy appears to be durable. We play in short increments but enjoy the toy.

Must get!, Great interaction, mind stimulation
Color: Orange
Love this my pup can't get enough. My pup loves this and is hard on it. She throws it all around chases it and guards it like it is her child. It is strong, sturdy easy to charge and fun to watch her engage with it. Definitely must have and I will buy more. It shakes and rolls around, it walks itself and engages the pup to chase. The design is spectacular. It is light weight and the noise level is typical of a toy engaging response.

Awesome for hyper dogs
Color: Blue
AWESOME - I have a dog that just won't stop trying to get me to play with him ALL day! I turn this thing on and he goes nuts and tires himself out...without any help from me. The cover got torn off and torn up in minutes but he doesn't care. He just wants this ball. My other dogs, who are older, aren't really interested. But if you have a hyper dog this is the thing for you and them!

Great entertainment, charges quickly!
Color: Orange
Super fun entertainment for dog! Toy ball charges quickly and the charge lasts for at least an hour of playtime for the dog. There are 2 modes. one mode Just lights up, which makes it easy for pet to chase it. The second mode not only lights up, but it also wiggles on the ground Randomly and speeds off in a direction on its own, which really makes it interesting for your dog or cat to follow! Once the ball is not touched for about thirty seconds, it goes dormant and it will stay like that As long as it's charged until somebody touches it, and then it starts up randomly lighting up and moving around the floor on its own And making a vibration noise. It's a lot of fun to watch the dog chase and play with, and it certainly keeps them entertained for a while! The laughs and fun entertainment are definitely worth it. The only downside is that my dog chewed off the soft fabric covering in about twenty minutes.And she's not a real big chewer. It looks better with the covering on it, but even without it, the ball works fine and she plays with it every day.So that is not a showstopper. But good to supervise your dog for safety.In case they are a chewer, and they decide to destroy the cover. But the ball works fine without the cover too!
