Synthesis of carbon nanotubes by direct irradiation of microwave signal

The proposed method of CNT synthesis is simple, fast and economical while further investigation is underway for a uniform synthesis of CNTs on a relatively large area. Current tends to be much stronger at the edges of metal strips and due to this edge effect, uniform heating of the metal catalyst layer is difficult to achieve. Parallel metal catalyst lines, instead of a single metal catalyst layer, is beneficial to circumvent the edge effects. Besides the edge effect, there are many other conditions and parameters that affect the absorption of microwave energy by thin metal films. Computer simulations were used to investigate the effect of these other variables.
