Name:Industrial grade  MWNTs 20-40 nm


Product Overview

Multi-walled carbon nanotubes are made of multilayer coiled graphene sheets and maintain a fixed distance between the layers, forming a coaxial circular tube structure. The tube diameter is usually between 5 and 30nm, and the length can range from a few microns to dozens of microns. The specific size depends on the preparation method and conditions. The purity of industrial-grade MWCNTs can reach 95% or higher, ensuring their stability and reliability in applications. The main preparation method of industrial grade multi-walled carbon nanotubes is chemical vapor deposition (CVD) method. In the process of CVD, carbon source substances (such as methane, acetylene, etc.) are decomposed and deposited into tubular structures under the action of catalysts (such as iron, cobalt, nickel, and other transition metals at high temperature). Precise control of the diameter, length and structural properties of MWCNTs can be achieved by controlling reaction conditions and the use of specific catalysts.

Product Features

 

1)Mechanical properties: Industrial-grade multi-walled carbon nanotubes have extremely high strength and toughness and are considered the super fibers of the future. It is 100 times as strong as steel and weighs only 1 / 6 of steel, giving it great potential for composite enhancers.

2)Conductivity: Multi-walled carbon nanotubes have good electrical conductivity, even better than copper. This makes it widely used in electronic devices, conductive inks, sensors and other fields.

3)Thermal conductivity: multi-wall carbon nanotubes also have excellent thermal conductivity, their thermal conductivity is much higher than the general metals and alloys. This makes it have an important application value in the thermal interface materials, heat dissipation materials and other fields.

4)Chemical stability: Multi-walled carbon nanotubes have good chemical stability and can maintain their stability in a variety of harsh environments.


Application Fields

 

1)Electronic devices: Multi-wall carbon nanotubes can be used to manufacture high-performance conductive inks, sensors, flexible displays and other electronic devices. Their excellent electrical conductivity and mechanical properties enable these devices to have higher performance and longer service life.

2)Energy storage and conversion: Multi-walled carbon nanotubes can be used as electrode materials for lithium-ion batteries and supercapacitors to improve energy storage and power output capabilities. Its high specific surface area and excellent electrical conductivity make the electrode material have higher energy density and faster charge and discharge speed.

3)Composite materials: In composite materials, multi-wall carbon nanotubes as enhancers can significantly improve the mechanical properties and electrical conductivity of materials. They can be added to plastics, rubber, metal matrix, etc., to enhance the strength, stiffness, and thermal conductivity of the material.

4)Other fields: multi-walled carbon nanotubes can also be used as catalyst or catalyst carrier, hydrogen storage materials, thermal interface materials, etc., which has a wide application prospects in chemistry, energy, environmental protection and other fields.

Nice tactile feel
Style: 2024 Model
Works right out of the box. Installation was simple. Probably should have gotten the next small size, as it is larger than I expected. But I like the key response and the feel of the mouse, so I'm keeping it. Nice, inexpensive keyboard and mouse.

Well, Logi (Logitech)'s normally great record has been broken...
Style: 2024 Model
Gotta vent. I've had my Logitech K800 forever and a day and LOVED it. Never any performance problems, smooth, comfortable, easy to use, and took a beating daily for years. Got it through work, so it was more expensive than your usual, but it couldn't last forever. It started being unable to take a charge, so I knew I would have to retire it. (They stopped making these (WHY???) and they're selling after-market for a fortune.) I have Logi all things keyboard, mouse, etc., so went with them again. Bought a K650, but out of the gate, it started doing weird stuff, like repeating keys when you weren't even touching the keyboard, jamming up, or just stopping functioning. Did all the usual troubleshooting, but nothing worked. Just to save time, I sent it back here and replaced it with an MK540. Son of a gun if it didn't start immediately doing the same things. NOW I was cranky, so I did my online research and learned these are well known problems for others, who also couldn't solve them. I then went to Logi tech support. Got a level 1 person who walked me through the standard steps I'd already done multiple times (Did you turn it off and on again? :-D), gave me long lists of things to try, then at the end, when nothing worked said, "Well, it's within 30 days so just return it to the seller, and here's a link to our other keyboards." "Ummm," I said, "this is the exact same circumstance with two DIFFERENT keyboards in a row. As I had no trouble with my previous Logi keyboard, and nothing else has changed on my end, it seems logical that the problem is with the new software, hardware or some QA problem with producing these models. Why would I go buy another one when we don't know WHY it's doing this, suggesting I could go through this all over again?" (BTW, a MAJOR inconvenience for days). Her answer (twice): "Don't worry, it'll be fine, just go get another one." OMG. Stubborn, so I gave it a third shot (MX Mechanical) now for 3x the money hoping better quality would help, but guess what? I've now received my 3rd notice from Amazon saying delivery will be delayed, this time with no date estimate known. I tried, Logi, but even I am done. Buying a highly rated other keyboard that has all the features I need. Logi, not sure what you're doing with these membrane ones (vs. mechanical), but it's not working. If you could ship me a K800, I'd so appreciate it. :-D K

Perfect keyboard with wireless Unifying Receiver
Style: 2024 Model
I've tried and had to return multiple $100+ keyboards due to irregular F1-F12 or arrow key layouts, dreaded Fn key in the lower-left, mushy key travel feel, etc. I've been using exclusively Logitech keyboards & mice since the 90's, but gave up and tried venturing to other brands like Keychron (had issue with inadvertent key presses when pausing fingers over keys). But this simple keyboard just gets it right. I didn't even need the bundled mouse since I use Logitech MX Master 2S, but like that I can use the same Logi Unifying Receiver and Options+ software (optional). There are dedicated keys: * power on/off colored slider * play/rewind/ff * volume mute/down/up * calculator * battery level * 2 user-configurable buttons * Fn+ F1-F8 are also configurable The are 3 height levels, built-in mini palm rest (I still use a big keyboard mat beneath), slot for Unifying Receiver and 2 AA under the battery cover. Minor issue is the batteries clack when using the F5-F12 keys (just below where the batteries are), but I taped a little strip of foam on the inner side of the battery cover to resolve it. Also great is Logitech MK270, which is more compact, light, and perfect for the road. Both have amazing battery life.
