一般描述

Aspect ratio: > 350-550 (determined by AFM)
Number of Walls: 6-8 tube walls (typically). Multi walled carbon nanotubes (MWNTs, CNTs) were prepared by chemical vapor deposition (CVD) using cobalt and molybdenum as catalysts (CoMoCAT).In chemical vapor deposition (CVD), a volatile precursor undergoes thermal decomposition at elevated temperatures to form a solid deposit on a substrate. Compared to other techniques CVD produces greater yield of carbon nanotubes. Morphology and structure of the nanotubes can be easily tuned using CVD technique. The CNTs formed can be formed in bundles over a catalyst support or in patterns over substrates.1

应用

Carbon nanotube, multi-walled (MWNT) belongs to the class of carbonaceous materials with excellent physiochemical, 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.
New generation of specialty multi-walled carbon nanotubes enable polymer composites with higher conductivity;easier to disperse and mechanical properties for advanced applications like conductive polymers or Li-ion battery cathodes.
