MSE PRO™ High Purity (>99.9 wt%) Graphitized Carboxylic Multi-Walled Carbon Nanotubes, 30g


Graphitized Carboxylic Multi-Walled Carbon Nanotubes (MWCNTs) are purified under inert gas for about 20 hours thermal treatment at 2800℃. 

The Carboxy functional groups on the surface of Carbon Nanotube (CNT) can not only improve their dispersion in solvents or polymer, but also act as reactive sites for further chemical modification. Graphitized Carboxylic MWCNTs can be used in various fields including additives in polymers, catalysts, electron field emitters for cathode ray lighting elements, flat panel display, gas-discharge tubes in telecom networks, electromagnetic-wave absorption and shielding, energy conversion, lithium-battery anodes, hydrogen storage, nanotube composites (by filling or coating); Nanoprobes for STM, AFM, and EFM tips, nanolithography, nanoelectrodes, drug delivery sensors, reinforcements in composites, supercapacitor.

Keep dry at room temperature.

MSE Supplies offers a variety of CNT products, include CNT powder, CNT paste, CNT array, CNT fiber, CNT film, CNT film adhesive tape, CNT conductive heating coating, CNT thermal radiation coating, CNT transparent static conductive coating, CNT conductive fillers, CNT functional masterbatches, CNT epoxy composite, etc. Please contact us for more information.
