Name: Carbon Nanotube sponges


Product Overview

Carbon nanotube sponge is a kind of three-dimensional spatial network structure formed by the overlapping of numerous carbon nanotubes, which has low density, high porosity, good mechanical properties and super hydrophobic and oil-wet surface characteristics.

Due to its high porosity and hydrophobic lipophilic properties, carbon nanotube sponges can be used to adsorb and separate various organic substances, such as organic solvents, oils, etc. It can quickly absorb and store a large amount of oily substances, and can be released by extrusion to achieve reuse.

The high surface area and pore structure of carbon nanotube sponge make it a good catalyst carrier. The catalyst can be loaded on the sponge to improve the activity and selectivity of the catalyst.

Using the electrical and mechanical properties of carbon nanotube sponges, sensors can be prepared for the detection of physical quantities such as pressure, strain, humidity, and chemical substances.

Carbon nanotube sponges can be used as electrode materials for supercapacitors or lithium-ion batteries to improve the performance of energy storage devices.

Product Features

Low density: The density of carbon nanotube sponges is very low, usually only about 1% of water.

High porosity: It has extremely high porosity, and the porosity can reach more than 99%.

Good mechanical properties: carbon nanotube sponge has good mechanical properties, and can be repeatedly compressed and compacted and still be able to restore the original shape.

Superhydrophobic and lipophilic surface properties: Carbon nanotubes and their macrostructures synthesized at high temperatures have superhydrophobic and lipophilic surface properties. Therefore, the carbon nanotube sponge can be directly put into use without complicated chemical modification treatment, and can strongly absorb oily molecules without absorbing any water in the case of oil-water mixing.

High adsorption capacity: Carbon nanotube sponges can quickly absorb and store a variety of organic solvents and oils (gasoline, diesel, lubricating oil, vegetable oil, etc.) equivalent to 80 to 180 times their own weight.

Controllability: By changing the preparation conditions and methods, the porosity, pore size and density of carbon nanotube sponges can be regulated to meet different application needs.

Electrical conductivity: The carbon nanotubes are bonded to each other to form a highly conductive three-dimensional network, making the carbon nanotube sponge have good electrical conductivity.

Stability: Carbon nanotube sponges can resist high temperatures of several hundred degrees in air, and are extremely stable in hostile environments or seawater.


Application Fields

Pressure sensors: With their super-elastic and adjustable sensitivity properties, they can be used to prepare pressure sensors with a wide range of customized sensitivity.

High performance energy absorber: The unique crack-induced hyperelastic mechanism of carbon nanotube sponge enables it to effectively absorb impact energy, which can be applied to the development of high performance energy absorber.

Oil-water separation: can selectively absorb oil molecules without absorbing water, can be used in the field of oil-water separation.

Environmental remediation: It can be used to adsorb and remove organic pollutants and heavy metal ions in the environment.

Energy storage field: Carbon nanotube sponges can be used as electrode materials in energy storage devices such as supercapacitors and lithium-ion batteries.

Functional composites: By combining them with other materials, functional composites with special properties can be prepared, such as enhancing the interface properties of carbon fiber composites.

Smart textiles: Using their good electrical conductivity and flexibility, smart textiles can be developed, such as wearable sensors or energy harvesting devices.

Aerospace: Its lightweight, high-strength characteristics make it a potential application in the aerospace field, such as the manufacture of structural components for spacecraft or thermal protection materials.

Great formula, but the packaging wears off too fast
Color: 260 DEEP BROWN, Size: 1 Count (Pack of 1), Color: 260 DEEP BROWN, Size: 1 Count (Pack of 1)
This Maybelline Build-A-Brow pen makes it really easy to create natural-looking brows with precise strokes. The color applies smoothly, blends well, and stays in place for hours without smudging. I like that it helps fill sparse areas without making the brows look too heavy or fake. The 2-in-1 design is convenient and perfect for quick everyday makeup looks. 10/10 I need to buy again

Very pleased! Works great!
Color: 262 BLACK BROWN, Size: 1 Count (Pack of 1)
I have tried a lot of products before this and it's hard to find a color that doesn't have a red hue to it. I got the black brown and it's a great color that doesn't have any red tint. It was super easy to get hair-like strokes. To keep the beginning of the line thin just hold the tube farther back and apply with a light touch in a short flicking motion. It dries quickly and is resistant to smudging. I rubbed decently hard with my finger and the product stayed in place. I didn't do any prep to my brow area before applying this product except for wiping the area with water and drying it. The lines stayed crisp after drying and didn't blur out like some products tend to. There is no noticeable smell, you can't feel the product on your brows/skin after you apply it and it dries matte. The sealant that it comes with doesn't have any noticeable smell either and doesn't feel tacky or hard after it dries. Also, neither product leaves any gloss or shine on the skin once they dry. Everything is nice and matte and feels like there's nothing there. This pen has given me the most realistic results I have ever received from these types of products. I would definitely purchase this again!

Awesome brow liner and gel
Color: 259 ASH BROWN, Size: 1 Count (Pack of 1)
Love this pen! Just wish there was a color inbetween the medium brown and the ash brown. I love the brow gel in it though! The pen is nice and makes hairlike strokes that make for a more naturally filled in brow. The gel holds in place all day!

Benissimo!
Color: 250 BLONDE, Size: 1 Count (Pack of 1)
Hands down the best brow pen I’ve used & I have used ALL of them! I love this for my almost non-existent brows. It’s easy to handle for precise hairlike application. Have subscribed to this it’s so good. Finally, one that’s the right color, doesn’t run out even after a month of use & is the BEST price. Maybelline for the win!

The colors are way off
Color: 259 ASH BROWN, Size: 1 Count (Pack of 1)
The ash brown is basically black. However, I do think the gel helps set the brow color and I have been using a ash blonde color and then applying the gel.
