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.

Pretty cheap but surprisingly solid
Color: Black
This thing comfortably fits my 16” MacBook Pro. It does tilt a bit probably due to me screwing it to the underside of my wooden desk which probably isn’t the exact use for it, but it holds really strong and isn’t going anywhere. Combining this with a small USB-C hub for some USB As and and extra HDMI and a little bit of Velcro, this holder makes for a pretty solid option to hide you laptop away if you a surprisingly clean desktop-like experience, even if you’re on a budget and can’t afford a desktop. A proper thunderbolt docking station would go a long way with this as well.

Works as advertised
Color: Black
Functions as described. Looks good. Laptop fits in loosely. I’d prefer a more snug fit. Other than that, works as advertised.

Genius solution for a cleaner, more organized desk
Color: Transparent, Color: Transparent
This mount completely transformed my workspace. I was looking for a way to get my laptop off my desk without buying a whole new piece of furniture, and this delivered. The clear design blends into any space so it doesn’t look clunky, and installation was easier than I expected. My laptop is secure and easily accessible, and I’ve freed up so much desk real estate. If you’re trying to create a cleaner, more minimal workspace, this is a great purchase. We did have to screw it in place because the sticky side came off after a few days, but I think it’s just the temperature fluctuations in my office.

Perfect for my daughter's Chromebook!
Color: Black
Comes with adhesive and screws. I chose to use the adhesive and it works great. My daughter got a Chromebook for school and its a great place to put it so we charge it when she gets in from school and remember to grab it before she leaves! Very easy installation, so far pretty sturdy, great price, and it fits perfect because you can adjust to whatever size you need.

Great fit and finish, quality hardware, well worth it!
Color: Black
Great product. It seem like it would probably fit most modern size laptops. He adhesive mounting tape seems very strong, but I used the screws for extra strength. Comes with it all…hardware and screwdriver. The plastic is quality and built strong. I had to trim on of the slots in the side to accommodate my computers plug, but that’s not the fault of this product. I would recommend this absolutely.
