How do you cut carbon nanotube fibers and yarns?

CNT fibers and yarns are highly aligned from end to end and can be successfully cut to length with very simple tools such as a razor blade.

Due to the highly aligned nature of CNT fibers, they are hard to cut to length.

when a clean cut is required, using a sharp razor blade you can press the blade into a sacrificial surface under the fiber/yarn and lightly saw back and forth to slice leaving a clean cut.

Alternatively, if laser equipment is available you can cut the fibers/yarns using a standard co2 laser. 

20w should be enough to cut most yarns offered in our store with modifications to speed when thicker yarns are being cut.

Please see video below for a quick demonstration on how to cut CNT yarn using a razor blade
