Product Features

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.

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

Oh how I love this little Gem
Color: Silver
I needed this badly as I often got irritated with the kids for putting the sponge back in the soap/scrubber dish and it was always full of water. I looked at options on the side of a sink but none were quite right for our set up...Then I saw this. What I love is it is not one more thing on the counter. It is below down in the sink. And yet, it is handy. Into it I have the essentials I use so many times a day right there handy and they drain on their own. This adhered well because I used rubbing alcohol to clean the area, then waited several hours before adhering set up to sink about 10 pm at night. Letting it set over night and in the morning I remembered the tip another reviewer wrote to push the tray down STRONG until it CLICKS into the holders. Then it was completely sturdy and firm and I've used it long enough to know I'm very happy for this small perfectly practical way to hold my sink tools. So glad I chose this much less expensive simple one.

Highly Recommend
Color: Silver
Love this holder of all the things! We purchased this 4 years ago and it has work great, rust-free, until my husband piled two pots on it and it broke last night. I am immediately purchasing another one. It is very easy to install and stays put, no movement at all.

Works well
Color: Silver
The stainless steel caddy quality is fine, the sticker was easy to install on the inside of my stainless steel sink. I initially used the small movable arm to hang on the hooks, and it did not keep the caddy in place. Anytime it was hit, it fell off or tilted off the hooks. Customer service followed up with me on my purchase, gave me the correct instructions with a picture, and I was able to snap the caddy into the hooks. They were responsive, listened to my concerns and answered my questions, and now it works great. I would recommend this.

It doesn’t take up so much space
Color: Silver
This is perfect for my use. I did have to place the sticker on it to hold it in place. I have a Blanco sink which isn’t smooth.
