Graphene is carbon in a 2d lattice. It is 250x stronger than steel, it conducts electricity, it is adhesive, it is light, it is transluscent, it is elastic, and it is flame ******ant (by the way, you can buy graphene online, but I want the magnesium oxide). As for nano-cellulose, I don't know. There are two different kinds. One is burned by an acid, and the other is mediated through tempo. Tempo is the best, but I'm still working at finding it.
The newest form of it is still in research. The nano-cellulose created through an oxidizer was a new idea. Factories are now just starting the production of it, and just 6 months ago, they modified it to make it as strong as kevlar. I think we are going to have to wait, at least until I can find a scientist who would email me about it. I did actually find a scientist who got into an in depth discussion with graphene, and another scientist for spidroin.
