Creating CNTs from Graphene ?

[Widdekind]

Could you create a single sheet of graphene:

 

and then 'hydrogenate' one edge (H-C), whilst 'hydroxylating' the other edge (C-OH), and then 'roll the sheet up' into a tube (center images),

 

allowing the Hs & OHs to 'jump off', as waters, leaving the tube 'sutured together' ??

The short answer is, no. You can, however, selectively funtionalise the ends of a carbon nano-tube.

 

Here are a few papers, though you may not have access to all of them:

Why exactly would you want to do this (functionalise the ends of a graphene sheet and turn that into a CNT, that is)?

 

ETA: I also found this, which I think you will have access too: http://snml.kaist.ac.kr/jou_picture/PDF/85.Tailored%20Assembly%20of%20Carbon%20Nanotubes%20and%20Graphene.pdf

Is there an "easy" way, of "rolling" graphene sheets, into CNTs? I would want an "easy" way, of manufacturing CNTs (which are long, linear, "rolled up strips" of graphene).
