Name :Low purity carboxyl SWCNTs (long)


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.

Must have
These things a freaking AWESOME! If you're doing a big sound deadner job, you need thees! The 3 different sizes are perfect for the different shapes in the floor pans. Well built, good quality and they have a nice weight to them. Just buy them and thank me later. For $15.00 you can't go wrong.

Bringing a 1976 MG Midget to the modern world!
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
I've been restoring a 1976 MG Midget barn find. I bought some Sinless liner to help make the car rattle less and feel more solid. This product is easy to cut, easy to install, and extremely sticky. I used it to line the trunk, the interior, and even some under the hood of the old MG. The adhesive stands up to the brutal temperature of the engine bay, and when (by accident) some fuel spilled onto the foam, it didn't fall apart or turn to mush. Thanks to Siless, the MG now feels like a modern car. The floor pans feel much more solid, the doors make a heftier thud when you close them, and the trunk no longer sounds like a percussion instrument when you touch it. If you know what you're doing, this product will transform the feel of a car. I found that 36 sq ft was enough for my MG Midget, but for a bigger car I would want more. The pattern on the back helped me to cut perfectly measured squares and rectangles. The foam itself doesn't have a strong odor, it works super well, and has held up to several months of changing temperatures (in the Midwest US.)
