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.

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

It has good flexibility and elasticity and can withstand large deformation without breaking. For example, in some micro-mechanical parts, complex movements can be achieved using their flexibility.

Electrical properties:

It has good electrical conductivity, and the electrical conductivity can be close to copper.

Exhibit unique quantum conductivity properties. For example, in nanoelectronic devices, their conductance characteristics contribute to precise current control.

Thermal properties:

The thermal conductivity is very high and can effectively conduct heat.

Good thermal stability, can still maintain the stability of structure and performance in high temperature environment. This makes it a potential application in highly efficient cooling materials, such as the cooling components of high-power electronic devices.

Chemical properties:

High chemical stability, not easy to react in most chemical environments.

The surface can be chemically modified to meet different application requirements. For example, it can be better dispersed in certain solvents or substrates through chemical modifications.

Optical properties:

It has unique optical absorption and emission characteristics in the near infrared and visible regions.

It can be used to make optical sensors and light-emitting devices.


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.

We have a new favorite
It is a soft rubber material with a really loud squeak. Asuka loves to run around the living room squeaking over and over. She loves it so much she hasn’t shared it with the humans yet. She is an aggressive chewer and it is holding up well.

Enthusiastic Chewer Approved
Color: 2PC-Bacon-Green, Color: 2PC-Bacon-Green
You would think that a two pack of chew toys would be a great option for a household with two aggressive chewers but the dogs still fight over the toys. They seem to really love them an are choosing these first among several tough chew toy options. I can't speak to whether there is a bacon flavor but they did seem to have a slightly smoky smell to them when they arrived. The girls have been working hard on them for about a week and while they certainly show teeth marks, they appear to be holding up well. The size is nice for medium to large dogs and the shape lets them hold on to it while getting an angle at the apple knobs on the opposite end. The only downside, if I had to name one, is that they are heavy and if (when) your bestie drops the toy on your bare foot, it smarts.

Tough Toys That Keep My Dogs Busy
Color: 2PC-Bacon-Green
I cannot personally confirm the bacon flavor because I am definitely not going to taste these myself, and I did not notice any bacon smell when I opened the package. That said, my dogs seemed interested in them right away, so whatever scent or flavor they contain appears to be appealing enough for canine approval. What impressed me most was the durability. These toys are much tougher than many chew toys I have purchased in the past and have held up well to regular chewing. My dogs enjoy carrying them around, chewing on them, and staying occupied with them for extended periods. The size works well for medium to large dogs, and the material feels sturdy without being excessively heavy. While no toy is truly indestructible, these seem capable of handling some serious chewing. For the price, getting two durable chew toys is a good value. If you have dogs that enjoy chewing and need something a little tougher than the average toy, these are worth considering.
