Name:Carboxylic Multi-walled Carbon Nanotubes


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.

Hallelujah… finally, I found the right pillow!!!
Size: Queen (Pack of 1), Color: White
I have spent a lot of money searching for the right pillow. I recently tried to Tempur-pedic that cost twice with this pillow cost. Tempur-pedic flattened out. I’ve had this pill for a few weeks now and it works wonders. I am a paraplegic. You can have a lot of neck problems. I love the fact that this pillow is adjustable. I immediately saw it was too stuffy and took a bunch out. It works perfect so glad I didn’t spend money on a $200 purple pillow. I read a lot of reviews and there were a lot of complaints about the odor. Mine did smell funny when it came out of the box. I immediately threw it in the dryer with a few bounce fabric sheets came out smelling fine. Pillows are a very individual thing, but I think for 40 bucks this pillow is worth a try. I’m really enjoying mine about one of those silk pillowcases to go over it and it sleeps cool and comfortable. Best wishes in your search for the right pillow. Update: I’ve been using this pillow several months and it continues. Give me a good night rest pain-free.. well worth the money. UPDATE: I have been using this pillow for three months and it still works great. It does not flat out or get hot..

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

Best Pillow Ever
Size: Queen(Pack of 2)
I am absolutely obsessed with these pillows! They have the perfect balance of firmness and softness, providing amazing support for my head and neck. I've never slept better, and I can honestly say I'd order more in a heartbeat. These pillows are a game-changer for my sleep quality. I highly recommend them to anyone looking for the ultimate comfort.
