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.

Great for pore reduction
Color: Cyano Pink Spicule
This product works great!! it almost feels like an exfoliator. It reduced the pours on my nose, which were very big and now you can barely see them. I would recommend this product if you have large pores also make skin look firmer and smoother more for a night cream though.

More than expected
Color: Cyano Pink Spicule
Love, love and recommended to friends. Leaves my skin feeling and looking great. At 69 I don't expect miracles but can definitely see an improvement in texture, glow and line minimizing. I'm hooked and will never be without!

Micro-needling effect!
Color: Cyano Pink Spicule
Love how you can feel the micro-needling effect. I use this is my first application after toning and follow up with my serum and moisturizing routine. I do believe it gives my face a plump feeling, especially after gua sha. Will continue to use in my daily!

Helps my moisturizer absorb better
Color: Cyano Pink Spicule
I’m not quite sure if the product is fully working the way it is supposed to but I do like that when I use this and the apply moisturizer, it absorbs into my skin better and leaves my skin smoother and a lot less greasy. It’s easy to throw in my travel bag because of the size and you really only just need a little for each use so it goes a long way got the cost.

Amazing!
Color: Cyano Pink Spicule
This makes my skin feel so smooth. The appearance of my skin also is starting to look a lot better/younger. I've been using it for a week and a half already seeing changes.
