Product Name
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.
