Product Overview

Carbon nanotubes are simple substances composed of carbon atoms and can be regarded as hollow tubular structures formed by the curling of graphene. On the surface of carbon nanotubes, the carbon atoms are bonded to each other in the form of sp2 hybrid orbitals, which are arranged as hexagonal graphite layers. In theory, this regular hexagonal structure is perfectly evenly distributed over the entire surface of the carbon nanotubes. Topologically, the common structure and properties of graphene and carbon nanotubes are one of the important factors for their similarity. However, due to the curvature of the graphite layer in the carbon nanotubes, coupled with the defects that may occur during the growth process, the sp3 hybrid phenomenon may occur in the six-membered ring structure on the surface of the carbon nanotubes, resulting in the emergence of five-membered rings or seven-membered rings. Carbon nanotubes can be divided into single-walled carbon nanotubes, double-walled carbon nanotubes and multi-walled carbon nanotubes according to the graphite sheets with different number of layers.

Product Features

 

Multi-walled carbon nanotubes have many unique properties:

Excellent mechanical properties: very high strength and toughness. For example, its theoretical strength can reach tens or even hundreds of times that of steel.

Excellent electrical properties: Can show good electrical conductivity, depending on length-diameter ratio, structure and preparation method.

Good thermal performance: high thermal conductivity, can effectively transfer heat.

Large specific surface area: This makes it a potential application in adsorption, catalysis and other fields.


Application Fields

 

1. Composite material strengthening: multi-wall carbon nanotubes have high strength and toughness, adding them to plastics, rubber, metal and other substrates can significantly improve the mechanical properties of the material, such as strength, stiffness and so on. For example, the multistage structure obtained by grafting carbon nanotubes on the surface of carbon fiber can enhance the interfacial interaction with organic matrix and the mechanical properties of composite materials.

2. Electronic devices: Although its electrical conductivity is not as single and excellent as that of single-wall carbon nanotubes, it still has good electrical conductivity and can be used to manufacture high-performance conductive inks, sensors, flexible displays and other electronic devices.

3. Electrode material: It can be used as electrode material for lithium-ion batteries and supercapacitors to improve energy storage and power output.

4. Catalyst and catalyst carrier: itself can be used as catalyst. It can also act as a catalyst carrier, and because of its large specific surface area and special structure, it can provide more active sites for catalytic reactions and improve catalytic performance. For example, acidified multi-walled carbon nanotubes can be used as a carrier to support composite inorganic salts, and the solid acid catalyst produced has better catalytic effect than single-component iron sulfate.

5. Energy field: In addition to the previously mentioned applications in batteries, it can also be applied to hydrogen storage materials. The unique hollow structure and diameter of carbon nanotubes provide favorable conditions for hydrogen storage.

6. Wave absorbing material: It has a certain absorption capacity for electromagnetic waves, and can be used to prepare wave absorbing materials, which has potential application value in military stealth and electromagnetic shielding.

7. Biomedicine field: Its unique hollow structure and nanotube diameter can provide space for containing drugs, can achieve a high drug load, and can pass through cell membranes and a variety of biological barriers to deliver drugs to the interior of cells. In addition, it can effectively reduce the drug release rate and improve the sustained release effect.

8. Scientific research: It is often used in various scientific research to help researchers explore the properties and potential applications of nanomaterials.

I always ignore the buyer beware post but this is a buyer beware post!
I purchased this product based on the reviews I read. Please do not purchase. The cartridge is totally different from the brand version The part of the cartridge that should be fastened and locked into the pen is shaped in a circle , on the pen the Parr is rectangle . The original cartridge has a circular downward pattern to help lock the cartridge into the machine on the replacement cartridge there's no ridges it just slides down so it doesn't fit in no way shape form or fashion. I tried to alter the circular piece to make it fit by filing, burning and reshaping the plastic in an attempt to change the shape to a rectangle to fit it doesn't work the entire cartridge does not fit into the machine it's a waste of money for product that can't be returned or used. Buyer beware!

HE IS THE BEST WRITER, AND GREAT REFERENCE NOTES, DETAILS FOR STUDY
Format: Paperback
I CAN'T GET ENOUGH OF BRIAN SIMMONS BOOKS. THESE ARE AMAZING, THE FOOTNOTES ARE INCREDIBLY DETAILED AND HELPFUL -- YOU WILL LEARN SO MUCH -- THE WRITING IS REALLY REVELATIONAL IN ITS STYLE -- I LIKE THIS PASSION TRANSLATION A LOT! BUYING UP ALL THE BOOKS AS THEY ARE RELEASED AND THE 12 STUDY GUIDES -- THEY ARE ALSO AMAZING -- YOU WILL ENJOY THE WAY HE HAS SET UP THE STUDY AS WELL -- USEFUL. AS I SAID, GO BUY THIS, IT'S REALY A NICE BOOK. I CAN HARDLY WAIT UNTIL HE HAS THE WHOLE BIBLE DONE SO I HAVE IT ALL IN A BIBLE WITH ALL THOSE GREAT FOOTNOTES AND DETAILS. KEEP WRITING BRIAN! AND THANK YOU AND YOUR TEAM FOR THE GREAT WORK YOU ARE DOING!
