Product Overview

Carbon nanotubes, also known as buckytubes, can be viewed as seamless hollow circular tubes formed by winding a single layer of graphite hexagonal grid plane along chiral vectors, with carbon atoms typically capped at both ends in pentagons. Therefore, the carbon atoms in carbon nanotubes are mainly sp2 hybridized, and once the hexagonal network structure forms a spatial topology, a certain sp3 hybridization can be formed. The diameter of SWCNT is generally between 1-2 nm. Single walled carbon nanotubes can reach lengths of micrometers, even millimeters and centimeters, with a large aspect ratio and superior electrical, mechanical, and thermal properties.

Product Features

Excellent conductivity: It has excellent conductivity, high conductivity, low resistance, and can efficiently transmit current. For example, its conductivity can be comparable to excellent conductors such as silver and copper.

High thermal conductivity: It has excellent thermal conductivity and can quickly transfer heat. It has potential application value in electronic devices and thermal management systems that require efficient heat dissipation.

Unique mechanical properties: possessing high strength and toughness. The tensile strength can reach 100-200 GPa, and the Young's modulus can reach about 1 TPa, which makes them have great potential for enhancing the mechanical properties of composite materials.

Nanoscale effect: The diameter of the tube is generally around 1-2 nm, which has unique properties brought by small size. For example, due to quantum confinement and surface effects, they exhibit different characteristics from macroscopic materials in terms of interactions with other substances and electron transport.

High chemical stability: It has good stability in general chemical environments and is not easily reacted with acids, bases, oxidants, etc., which enables them to maintain stable performance in various complex application environments.

Diversified forms: Different forms such as bundles, films, and networks can be formed to meet different application needs.

Optical performance: It has absorption and scattering effects on specific wavelengths of light, and can emit light under certain conditions, which has potential applications in optoelectronic devices.

High flexibility: It can bend and fold without breaking, which has advantages in the manufacturing of flexible electronic devices.


Application Fields

In the field of electronics: Due to their unique electrical properties, single-walled carbon nanotubes can be used to manufacture smaller and more efficient integrated circuits, field-effect transistors, and flexible electronic devices.

In the field of energy, single-walled carbon nanotubes can be used as electrode materials in lithium-ion batteries, which can increase the battery's charge and discharge performance and cycle life; It can also be used to manufacture supercapacitors, improving the energy density and power density of capacitors.

Composite materials: Adding single-walled carbon nanotubes to polymers and other materials can significantly improve their strength, stiffness, and toughness.

Sensors: Utilizing their high sensitivity and selectivity towards gases and chemicals, they can be used to detect biomolecules and cells, among others.

Nanomachinery: Single walled carbon nanotubes can serve as key components for constructing micro machines, such as nanomotors.

Aerospace: Used for manufacturing lighter and stronger aircraft and spacecraft components.

Other fields: It also has applications in catalysts, field emitters, conductive films, and biological nanomaterials.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation. However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through. That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone. Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.
