Graphene has been identified as a potentially useful MNT product target.

To create a graphene sheet using mechanically induced SPM-based actuation, rather than existing chemical growth modes, you’d need some way to access the reaction site because it is an “edge” rather than a surface. It seems like a harder experiment than mechanosynthetic diamond bulk lattice build-up.

I’m thinking you might be able to extrude a middle (not outer nor inner) nested CNT slightly forward from the bulk of the MWCNT, to expose it. The idea being that as the middle CNT is being mechanosynthetically built up, it is extruded back into the MWCNT bulk. I’m hoping the same forces responsible for low friction between MWCNT “layers”, will also help to prevent dangling CNT edge dimers from reconstructing or otherwise reacting with surrounding CNTs.
