Multi Wall Carbon Nano Tubes
(MWCNTs)



Multi Wall Carbon Nano Tubes (MWCNTs) are generally, above all, a nano material. MWCNTs are ordinarily classified as 1-dimensional allotrope of sp2 hybridized carbon, similar to graphite & fullerenes. Ordinarily, MWCNTs, are finally, single-walled carbon tubes & are nestled one inside the other.

As a matter of fact, MWCNTs, have numerous novel & useful properties.

Above all, in particular, they have excellent mechanical & electrical properties. MWCNTs have therefore greatly diverse uses in industrial, & aerospace as well as medical applications.

Open ends of MWCNTs allow especially a fast electron transfer rate as compared to graphite. An easy dispersion ability is a key feature of MWCNTs.



MWCNTs are available Commercially & for Research

AIMCOMMWCNTs

(Commercially Available)

We present powdered MWCNT (AIMCOM), directly from the reactor system by thermocatalytic method & no purification from other forms of Carbon is required. The AIMCOM, MWCNTs are intercalated with Ni nanoparticles ~ 10 nm in size, due to this, they are magnetically soft ferromagnetic having low residual magnetization.

APPLICATIONS OF MWCNTs

Electrically Conductive Polymers

Use of MWCNTs in Electrostatic discharge protection in wafer processing & anti-static elastomeric components. Plastic components for automobile fuel line components & other uses are also exploitable. As plastic can be made conductive, electrostatic spray paint can be applied to automobile body parts. Also RFI shielding can also be achieved.

Battery Cathodes

Cathodes of batteries can make use of MWCNTs.

Structural Composites

Thermosetting resins when infused with MWCNTs exhibit increased stiffness & strength. Therefore they can be used as structural laminates & golf club shafts & also aerospace component manufacture.

Above all, have likely use in hair color products & other hair products as well as are capable of encapsulating hair dye molecules. Therefore this particularly helps producing stable Nano pigments. Above all, they can also be simply be added to make effective anti-lice preparations & besides anti-hair loss products for man & animals.

PROPERTIES OF MWCNTs

Some commercially exploited properties of MWCNTs are as under:

Electrical

MWCNTs exhibit high conductivity & outer walls are conductive but the inner walls are not.

Thermal

MWCNTs are thermal stable above 600 degree Celsius & this is due to defects in the structure & residues.

Chemical

Due to sp2 hybridization of carbons, they give excellent chemical stability to MWCNTs is provided Chemical reactions can provide functional groups & therefore strength. Therefore dispersion ability of MWCNT composites is increased.

Physical

Integration of MWCNTs into thermosetting & other thermoplastics can increase their strength multi-fold.

APPLICATIONS OF MWCNTs

There are evolved & evolving uses of MWCNTs :

Electrically Conductive Polymers

Use of MWCNTs in Electrostatic discharge protection in wafer processing & anti-static elastomeric components. Plastic components for automobile fuel line components & other uses are also exploitable. As plastic can be made conductive, electrostatic spray paint can be applied to automobile body parts. Also RFI shielding can also be achieved.

Battery Cathodes

Cathodes of batteries can make use of MWCNTs.

Structural Composites

Thermosetting resins when infused with MWCNTs exhibit increased stiffness & strength. Therefore they can be used as structural laminates & golf club shafts & also aerospace component manufacture.

Moreover, MWCNTs are now offered by us, for example, also in the Grades AIM1 & AIM2 & AIM3.

AIM 3 (Multi Walled Carbon Nano Tubes), above all, have likely use in hair color products & other hair products as well as are capable of encapsulating hair dye molecules. Therefore this particularly helps producing stable Nano pigments. Above all, they can also be simply be added to make effective anti-lice preparations & besides anti-hair loss products for man & animals.
