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.

Great case and keyboard
Color: Light Pink, Color: Light Pink
Omg. I LOVE this case and keyboard. It works so well and makes my iPad seem like a computer. It’s connects really well and I love the keyboard colors! I’ve been using it at work and it has been so great on saving notes and writing emails using the keyboard etc. And it’s very sturdy!

Made well but function is challenging
Color: Dark Cherry
I’m not so sure I really like this over all. The keys on the keyboard are nice, not mushy at all, very clear and functional. And the size of the keyboard is fine. It’s not full size and I didn’t expect it to be. But what I can’t get used to is how floppy the rest of it is. It won’t sit well in my lap, it must be on a flat surface to function at all. I find that very frustrating. The grooves that prop up the ipad won’t hold it if you move it at all. The keyboard must be unattached, moved and reattached to close up everything securely. Also it is heavier than I expected. The quality is good. It is not cheaply made. The color is just what I wanted and expected from the description. I’m giving it four stars instead of three because it is made well, but it’s mostly form over function. Edit: I returned this product and ordered a keyboard with the swivel holder for the ipad, much sturdier and steadier.

Purchased for the new iPad Pro size 11 inches
Color: Pine Green
I have a feeling that the people having issues may have the older model of iPad Pro! For the new model currently sold by Apple, the fit is good. The magnets & keyboard work perfectly. This is a great deal considering a lot of cases and keyboards cost just as much separately.

A bit disappointed
Color: Pine Green
Needed a new cover for my Ipad 11. This product had a good price, options for colors (I picked the green) and shipping was fast. When it arrived out of the box I was disappointed. Putting my Ipad 11 into the case was a bit harder than I expected. Once in, either the top or the bottom would not sat seated in the case. The backlight is nice, but you have to charge the keypad and ipad separately. I returned this because you have to physically move the keyboard to either use it or close the case or get the Ipad to stand. So, when closed the keypad sits right under the Ipad screen. When you open the case and want the ipad to stand, you have to physically slide the keyboard towards you or down to the bottom of the case. This then allows you to fold the upper portion and stand the ipad upright. You have to reverse this to actually close the case. What all this means is two things for me...this setup takes more deskstop space and a few more movements to get everything setup.
