Descrição geral

These are catalyst free arc-discharge multiwall carbon nanotubes (MWNTs). Multi-walled carbon nanotube core surrounded by a fused carbon shell, the remainder being multi-layer polygonal carbon nanoparticles and amorphous and graphitic carbon nanoparticles. It contains approximately 5-20 graphitic layers.

Aplicação

Carbon nanotube, multi-walled (MWNT) belongs to the class of carbonaceous materials with excellent thermo-mechanical and electrochemical properties. This material can be used in a variety of sustainable energy applications such as solar cells, photocatalysis, biosensor, gas sensor, supercapacitor and as a filler that acts as a reinforcement to improve the mechanical property of composites.
MWNTs were used in the comparative study of oxidative treatment to carbon nanomaterials. MWNTs were used as a reinforcement in CNT/SiC nano composites. 2
