Name:a>Industrial grade  MWNTs 20-30nm


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.


Technical Parameter

Length: 3-12um

Purity:>95wt%


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.

love! must buy!
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
Pro: Goes on white but fades and fades quicker when blended in. Gives meca slight bright effect on face overall. Hasn't broken me out - as far as i seen and known. No weird smell( mine did not smell at all). Not sticky, easy to blend on face. I feel it is worth the price especially because i feel like the ingredients are not overwhelming or harmful. Definitely a must buy! Con: Size, it is really small. I mean i knew it was going to be small in size but didn't imagine it be this small. (But i personally like the small size for use and storing in my bag or counter.) Definitely a must buy! Its cute, small, and useful.

Great for daily use under makeup
First, I'd like to say that this sunscreen stick is really convenient. It's moisturizing and blends in clear, so no white cast. Perfect for wearing under makeup, and it's non-comedogenic, so no worries about breakouts. Love how easy it is to apply and how lightweight it feels. Overall, a good choice for everyday sun protection.

Genuinely One of My Favorites Sunscreens in Existence
I use stick sunscreen around my eyes on a daily basis. It's less likely to run into my eyes and sting than regular sunscreen. However there can still be issues. Sometimes it still irritates my eye area, looks weird under makeup, pills, or (as with most mineral sunscreens) leaves a weird cast around my eye area. I was very pleasantly surprised by this sunscreen. It feels like very light weight balm that feels heavenly on the skin. It isn't sticky, greasy, and doesn't have a weird sunscreen smell. It's moisturizing without being too moisturizing, if that makes sense. Given the price point I am absolutely amazed at the quality. If you repackaged this sunscreen and sold it as a luxury product I would be none the wiser. This will be a new staple in my daily routine.

Good for on-the-go sun protection
This is a solid purchase because the compact size makes it easy to carry around. The velvety finish feels nice on the skin and blends in clear, which is great for all skin tones. It’s also quick and easy to apply.
