Product Overview

The preparation of carbon nanotubes by the CVD method is widely used with the advantages of mature method and high yield. However, the preparation of carbon nanotubes by CVD often requires the introduction of a catalyst, and the nanotubes grow in radial and axial directions with the catalyst particles as the centre. The catalyst is difficult to be removed, which becomes an important factor to restrict the improvement of the purity of carbon tubes, and will limit the application of carbon tubes to a certain extent. Graphitised carbon tubes are obtained by high-temperature treatment of ordinary carbon tubes in an inert atmosphere, which can effectively remove catalysts and other impurities, effectively improve the high purity of carbon tubes, reduce defects, and effectively improve their microstructure in order to obtain good electrical conductivity, thermal conductivity, mechanics and other properties. The higher the degree of graphitisation, the better the crystallinity of carbon nanotubes, and the thermal stability and electrical conductivity are usually better.

Product characteristics

High purity: Most of the metal impurities are removed under high temperature treatment of the carbon tube.

It has good flexibility and elasticity and can withstand large deformation without breaking. For example, in some micro-mechanical parts, complex movements can be achieved using their flexibility.

Electrical properties:

It has good electrical conductivity, and the electrical conductivity can be close to copper.

Exhibit unique quantum conductivity properties. For example, in nanoelectronic devices, their conductance characteristics contribute to precise current control.

Thermal properties:

The thermal conductivity is very high and can effectively conduct heat.

Good thermal stability, can still maintain the stability of structure and performance in high temperature environment. This makes it a potential application in highly efficient cooling materials, such as the cooling components of high-power electronic devices.

Chemical properties:

High chemical stability, not easy to react in most chemical environments.

The surface can be chemically modified to meet different application requirements. For example, it can be better dispersed in certain solvents or substrates through chemical modifications.

Optical properties:

It has unique optical absorption and emission characteristics in the near infrared and visible regions.

It can be used to make optical sensors and light-emitting devices.


Application Fields

Battery electrodes: Graphitised carbon nanotubes can be used as a conductive agent in lithium batteries to improve the conductivity and cycle life of the battery. 

Composite materials: by adding graphitised carbon nanotubes to matrices such as polymers, metals or ceramics, composite materials with high strength, high electrical conductivity and high thermal conductivity can be prepared. 

Electronic devices: Integrated circuits and display backplane driver devices based on semiconductor-type graphitised carbon nanotubes are being developed. 

Sensor devices: graphitised carbon nanotubes are characterised by high sensitivity and fast response, and can be used to prepare gas sensors, biosensors and so on. 

Electric heating devices: using graphitised carbon nanotubes' good electrical conductivity and electro-thermal conversion properties, highly efficient electric heating devices can be prepared.

Nice for the price
I am 6’4” and 195 lbs so I need a large size for most shirts. I need it for the length, but not the width, so shirts this size tend to bow out at the back and make me feel a bit like I am wearing a tent. I prefer polos made of a very thin, breathable and moisture wicking fabric. A decent looking shirt you can wear on hot and humid days without any undershirt and stay comfortable. Old Navy makes a fantastic version, very similar to the ridiculously priced Under Armor version, and I was hopeful that this Amazon version would compare. It does, but has a few drawbacks. If this sounds like you, keep reading. If not, thanks for getting this far. I’ll keep this brief with a list of pros and cons below. Suffice it to say, I like the polo enough not to return it, but it is still a step below some of the shirts produced by other outlets. Cons: 1. It is far from wrinkle free, though I’m not sure it is even touted to be. It does tell me, though, that this fabric won’t be as soft as I prefer. 2. The color is a little darker (I got the coral) than it seemed in the picture, but not terribly so. 3. The “slim fit” is what drew me in and while it better than most, the back still bows out a bit 4. The fabric is clearly moisture wicking, but not the light fluffy kind. I know I’m starting to sound like a snob, but if you know what I mean, you know what I mean. Sometimes a shirt feels heavy when you sweat in it. The idea of the moisture wicking fabric is to pull that sweat away as fast as you produce it to aid in the evaporative cooling taking place on your body. This shirt doesn’t feel heavy, but I’m not sure how long it will stay that way on a really hot and humid day. Pros: 1. Price. For $15, I can become blissfully ignorant to the cons listed above. 2. Fit. It isn’t perfect (Yes, I know this is listed as a con too), but if you have a tall, lanky body type like me, a large will fit you better than your average polo. After a trip or two through the dryer, probably even more so. 3. Convenience. Now that I know this is a good fit for me, I can try all the different colors I want from the comfort of wherever I choose to be with my phone.

2nd shirt purchased for golf team priced right slim fit comfortable
We needed golf shirts for being on the school golf team. Brand name golf clothing is extremely expensive and not worth it for a growing slim teen so our first purchase was this shirt in a different color. This is the 2nd shirt we've purchased after loving the first one. Good quality, value, and comfort. Easy wash and dry. Can be washed and thrown on a hanger to dry. No shrinkage. Perfect fit. This is a men's small that fits great on a person ~ 5' 10". The material is thin and does not hinder golf swings. Love that this shirt, and most Amazon clothing, has no brand markings. Wise marketing that Amazon's clothing is NOT labeled.

Great shirt & my son loved it.
Size: X-Large, Color: Blue
bought it for my son and he loved it. In fact when I called him he was wearing the shirt said it fit him well, it looked great. It was comfortable. He loved the quality & the cut. The length was great and ask me where I got it so I sent him the link so he could buy more in other colors. He loves to golf and said this is a perfect shirt for that. Plus the price was right.

sizing runs a bit big but very comfortable, i love these and ordered multiple colors
Size: X-Small, Color: Black
Initially, i ordered a small and an X small based on reviews here. Glad i did. I opened the x-small first and it fit perfectly. Returned the other one unopened. Sleeves fit my arms well. Collar stands up well. Shirt has sufficient length to tuck in too. Not super long though if you want to untuck with jeans. I'm 5'6 140#. I lift weights regularly and run. I'm right at 11.8-12.0% body fat. I typically wear a small in the amazon essentials slim fit t shirt. Those fit really well in size S. Check them out too if you have not yet. These polos XS fits equally well for my body type.

Great Shirt - Fits big and isn’t slim IMO
Size: X-Small, Color: Black, Size: X-Small, Color: Black
5’10, 155lbs, size X-Small. Soft material, very comfortable, light weight and breathable. Sizing is way off. This shirt is huge considering my size, shirt size, and slim fit.
