Product Overview

The CVD method for preparing carbon nanotubes is widely used because of its advantages such as mature method and high yield. However, the preparation of carbon nanotubes by CVD method often requires the introduction of a catalyst, and the nanotubes grow gradually along the radial and axial directions with the catalyst particle as the center. The difficulty of removing the catalyst has become an important factor restricting the purity of the carbon tube, which will limit the application of the carbon tube to a certain extent. Graphitized carbon tube is the ordinary carbon tube in the inert atmosphere of high temperature treatment, can effectively remove the catalyst and other impurities, effectively improve the purity of the carbon tube, reduce defects, effectively improve its microstructure, in order to obtain good electrical, thermal, mechanical and other properties. The higher the degree of graphitization, the better the crystallinity, thermal stability and electrical conductivity of the carbon nanotubes are generally 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 electrode: graphitized carbon nanotubes can be used as a conductive agent for lithium batteries to improve the conductivity and cycle life of the battery.

Composite materials: By adding graphitized carbon nanotubes to substrates such as polymers, metals or ceramics, composites with high strength, high electrical conductivity and high thermal conductivity can be prepared.

Electronic devices: Integrated circuits based on semiconductor graphitized carbon nanotubes and display backplane drivers are being developed.

Sensor parts: graphitized carbon nanotubes have the characteristics of high sensitivity and fast response, and can be used to prepare gas sensors, biosensors, etc.

Electric heater parts: Using the good electrical conductivity and electric heating conversion performance of graphitized carbon nanotubes, efficient electric heater parts can be prepared.

Good product for the price.
Size: 27"/QHD/200Hz
This monitor works great. I’ve used it for a while now and I haven’t had issues with this one. Screen size is good and refresh rate isn’t bad either.

Love These Monitors - Nothing But Love/Performance Here!
First and foremost, yes these are the BEST budget CURVED monitors I felt deservers my time, effort and money. I've been into electronics and computers since the beginning of BBS's. Lol. I wanted to upgrade and bought the dual setup during Amazon day. Blew me away. Couple tips I'll share so that you can get the Most out of these monitors. Tips: 1 - Don't buy CRAP cables. DON'T. Look at the specs, the refresh rates and what they are capable of - speed!!!; 2 - Make sure you have a GOOD quality GPU. If not you won't even be able to enjoy the investment of the these monitors. Invest in a GPU of at LEAST 8GB 1080p min with BOTH DP and HDMI ports.; 3 - With that being said, these monitors use MST!! Daisy chain them together off the DP port for an AMAZING viewing pleasure. If not, you CAN you both ports. Run your main to from the DP port (WAY BETTER quality than the HDMI) and the other using the HDMI 1.2. Again, CABLES ARE IMPORTANT. Crap cables = degregaged signal/sound loss. 4 - When you get it/them make SURE your GPU drivers are up to date. Configure on your operating system and BOOM.. ready to rock. I researched PLENTY of options and I'm ESTACTIC about these. I believe the deal I got was UNREAL for the price, QHD monitors and almost ..almost everything I needed. 1440p - incredible. Ebay/AMZ for a GOOD GPU card and cables.. well worth your time.

Great value and great monitor
Size: 27"/QHD/200Hz
As a note to new buyers: a chemical-like odor may be emitted from your monitor's exhaust for the first 2-3 weeks--at least mine did. I did some research and this was likely attributed to some cleaning chemicals from the factory, and it is burning off from the heat of the monitor. Simply have good ventilation in your room, and the odor should dissipate in 2-3 weeks. I've had this monitor for over a year now, and there is no odor anymore. Now, for the actual review: This monitor is great quality for the price! Not perfect, as I've found this monitor doesn't display smooth gradients of dark very well. For example, when I'm in a dark room in a video game, the dark ambient colors show slightly pixelated rather than smoothly blended. Other than that, this monitor works like a charm! Colors are great, and monitor settings are easily adjustable. One complaint I have is that I can't change the monitor's brightness using the Windows OS' brightness settings--you have to change the brightness/contrast using the monitor's buttons.

I bought this for my son as a second monitor. Graphics are sick! Feels like you're really in the game. My son absolutely loves it.

A great value for a state of the art monitor.
I use two of these at my home work station. I am not a gamer, I use these mainly for working on multiple spread sheets and financial programs. The high pixel count of these 8k video displays makes it easy to read the screens. I have Windows 11 on my computer, so installation of the 3 monitors was easy. I have my computer monitor set at 150% and these two monitors set at 125% magnification. All three are at eye level. They came with display port cables which my computer and hubs do not have, so I in a 8K HDMI cable for each. I do play a few videos, and those look great. The curved screen helps in keeping all the monitor sort of equidistant from my eyes which helps everything on the 3 screens stay in focus for my 80 year old eyes. I have reflections on my computer screen, but both of these Koorui monitors are reflection free. I first went to Costco to pick up a monitor and this allowed me to zero in that I wanted the 8k and curved screen in a 24 or 27 inch monitor. They did not have that combination. I tried just one of the Koorui monitors along with my older monitor. The Koorui was so far superior that I quickly purchased the second one and tossed out my outdated one. I use these for hours each day, and at this low price I feel I can easily justify this investment. I feel secure these monitors will be with me for a long time.
