Researchers Improve Electrical and Thermal Properties of Carbon Nanotubes
The preparation of carbon nanotubes via flame synthesis involves a modified combustion system with a carbon source, heat source and suitable catalytic material. To this end, constructing carbon nanotubes on copper (Cu) substrates via flame synthesis is a novel approach to achieve Cu-based carbon nanotube composites.

Cleaning and etching of Cu substrates with concentrated sulfuric acid is the first step towards Cu-based carbon nanotubes. The cleaned and carved Cu substrates were subjected to two different laminar flames using methane. The standard diffusion flame configuration (NDF) shows a blue flame, shielding a carbon-rich yellow flame
