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.

8. Research field: commonly used in various scientific studies to help researchers explore the properties and potential applications of nanomaterials.

Great buy would buy again
Size: X-Small, Color: Owl
Very durable dog toy. Lasted longer than any other toy with a squeaker for my wiener dog. Great squeak ability. Cute as can be.

Holds up well with aggressive chewers.
Size: X-Small, Color: Pig
This is my dog's favorite toy. And she has LOTS of toys so that is big endorsement. Miss Trina ( 40 pound boxer) loves to squeak it in Enzo's ( big brother 140 pound Cane Corso) face when he is sleeping. They also play tug of war . They destroy the toy eventually ( we are on the third one) but it holds for a few weeks. Miss Trina also likes to par corps around the house with this toy. Her favorite way to use this toy is bring it my husband for him to throw it . If he is napping she just drops in on his face. Definately recommend this toy.

Fun toy for my dogs but squeaker broke easily
Size: X-Small, Color: Pig
So far my aggressive chewer dog hasn’t been able to rip this toy apart but in one day she did break the squeaker inside. But I like that she hasn’t been able to rip it apart so it is pretty tough. I got this on a deal so it was good price for a toy that will last. Put 1 star down because the squeaker quality wasn’t the best when she was able to break it so fast. Esp love that it has no stuffing. And it’s a cute pink pig which is great.

My puppy loves this pig
Size: X-Small, Color: Pig
This pig is great! My puppy loves it. It’s fun to throw. It’s soft and furry on the outside with strong edges and very durable. We’ve had it 4 months while my puppy was teething and it’s as good as new. It’s adorable too! 5 out of 5 stars !
