Cheap Tubes

Cheap Tubes Inc (CTI) is a supplier of carbon nanotubes and graphene-based products including graphene CVD sheets, GNPs and graphene ink.

CTI was collaborating with American Graphite Technologies, and in March 2013 CTI (together with AGT) announced they have successfully produced graphene paper test samples which they call Bucky Paper. As far as we know that project is no longer pursued.
