A new, simple and effective method for cutting MWCNTs

Carbon nanotubes (CNTs) have attracted enormous interest in nanoscience and nanotechnology over the past decade owing to their unique chemical, mechanical, and electronic properties. The length of CNTs is of great importance for a variety of applications. Shortened CNTs are expected to have short dimension, richer chemistry and to be more easily dispersed. They are promising in the application of future nanoscale structures and devices.

It is demonstrated that an efficient and reliable one-step method using ‘nanoscissors’ was applied to cut MWCNTs. The cutting was promoted by interactive collision of CNTs with the SiC particles adhered on the abrasive papers, which broke intramolecular C-C bonds by external force. This process requires short operation time of only several minutes for cutting CNTs. It’s more important that the cutting effect was limited to the collision points, so cutting of CNTs could be achieved without severe damage of the CNTs which was different from above-mentioned mechanical and chemical processes. The present study provides a simple and effective method to cut MWCNTs which will broad their practical applications.

  1. This is indeed a good method!

  2. I have to say that for the last couple of hours i have been hooked by the impressive posts on this site. Keep up the wonderful work.
