Product Overview

 

Coiled Multi-Walled Carbon Nanotubes (CMWCNTs) are a kind of coiled multi-walled carbon nanotubes with special morphology. Their structure is characterized by the coiled coiled tube wall. Spiral multi-walled carbon nanotubes are formed by a plurality of graphite layers bent around a central axis and arranged spirally to form a continuous tubular structure. Each layer of graphite interacts with each other through van der Waals forces.

The appearance of spiral multi-walled carbon nanotubes shows a distinct spiral shape, which gives them unique physical and chemical properties. The preparation of spiral multi-walled carbon nanotubes usually involves complex chemical or physical processes, and chemical vapor deposition (CVD) is one of the most common methods for preparing spiral multi-walled carbon nanotubes. Under certain conditions, carbon source gas (such as methane, acetylene, etc.) is introduced into the reaction chamber, and metal catalysts (such as iron, cobalt, nickel, etc.) are used to decompose carbon source gas and deposit carbon nanotubes on the catalyst surface at high temperature. The morphology and structure of spiral multi-walled carbon nanotubes can be controlled by adjusting the catalyst type, concentration, reaction temperature and gas flow rate.

Product Features

Mechanical properties: Spiral multi-walled carbon nanotubes have high strength and modulus, and can withstand greater stress and deformation without damage.

Electrical properties: Spiral multi-walled carbon nanotubes have good electrical conductivity, and their electrical properties depend on their diameter, helicity and the number of layers. They may exhibit metallic properties, semiconducting properties, or insulator properties.

Thermal properties: Spiral multi-walled carbon nanotubes have excellent thermal conductivity, which can transfer heat quickly and maintain low thermal resistance.

Chemical stability: Spiral multi-walled carbon nanotubes have high chemical stability and can maintain the stability of their structure and properties in a variety of environments.


Application Fields

Composite materials: Spiral multi-walled carbon nanotubes can be added to the composite as a reinforcing phase to improve the mechanical properties and thermal stability of the composite. They have potential application value in aerospace, automobile manufacturing and other fields.

Electronic devices: Spiral multi-walled carbon nanotubes can be used to construct electronic devices such as field-effect transistors and sensors. Their high conductivity and adjustable electrical properties give these devices excellent performance.

Catalyst support: The high specific surface area and excellent chemical stability of spiral multi-walled carbon nanotubes make them the ideal choice for catalyst support. They can support a variety of metal or non-metal catalysts to improve the activity and stability of the catalyst.

Gas adsorption and separation: Spiral multi-wall carbon nanotubes have strong adsorption capacity for some gases, and can be used to construct gas adsorption materials or gas separation membranes. They have potential application value in air purification, water treatment and other fields.

Very comfortable, luxurious, and affordable.
Size: Queen (Pack of 2)
Great pillow. Feels soft enough for comfort while being cool and cozy. There could be more filling to make it slightly more firm but otherwise a great pillow.

Memory Foam Pillows
Size: Queen (Pack of 2)
recently purchased the OSBED Cooling Adjustable Shredded Memory Foam Pillow, and it has made a noticeable difference in my sleep quality. One of my favorite features is the adjustable fill, which allowed me to customize the height and firmness to perfectly support my neck and shoulders. Whether you’re a side, back, or stomach sleeper, it’s easy to find a comfortable setup. The cooling cover does a great job of preventing heat buildup throughout the night, which is a huge plus for anyone who tends to sleep warm. The shredded memory foam provides excellent support while still feeling soft and comfortable, and it doesn’t flatten out like some traditional pillows.

Great Quality, But Not for Me (Too Heavy & Hot)
Size: Queen (Pack of 2)
I want to start by saying there is absolutely nothing wrong with this pillow—it’s well made, good quality, and exactly as described. The adjustable shredded memory foam design and cooling features will likely work well for many people. That said, it just wasn’t a good fit for me personally. Right away, I noticed that the shredded memory foam pieces are fairly large and dense, which made the pillow feel heavier than I expected. When I laid on it, it didn’t have the light, airy “cloud” feeling I prefer. Instead, it felt more solid and structured. I also found it retained heat. Even though it’s advertised as cooling, memory foam tends to hold warmth, and I could feel that fairly quickly. For someone sensitive to heat, this may be uncomfortable. If you prefer a more supportive, denser pillow, this could be a good option. But if you’re looking for something lightweight and breathable, this may not be the best choice. Overall, it’s a quality product—just not the right match for my comfort preferences.

OSBED Cooling Adjustable Shredded Memory Foam Pillows Queen Size Set of 2
Size: Queen (Pack of 2)
The pillows were well packaged. They arrived when they said they would. The pillows are thick and they are cool. This makes for a nice long sleep night. I'm not constantly moving pillows around.

Cooling pillows
Size: Queen (Pack of 2)
I was skeptical with these pillows. I received the pillows compressed. I followed the directions and within 24 hours, I had 2 beautiful fluffy cooling pillows. I was also skeptical about the cooling techniques, i was happily surprised. With the support of my neck, the comfort of the pillows. I will be getting 2 more
