Cellophane (cellulose sulfate) is similar to cellulose acetate, sulfate verses acetate functional groups. It seems that the substitutions make the material soluble in common solvents (chloroform) which is the primary benefit (these materials don't seem to melt by heat very well). The solvent may also be recyclable. I think the bulk material will seem similar to other plastics, but a post hydroxylation treatment (to reverse the acetylation) would yield cellulose which could be quite strong. See the [Cellulose acetate] page. We also need research into the methods of dispersing the cellulose/solvent mixture. | Cellophane (cellulose sulfate) is similar to cellulose acetate, sulfate verses acetate functional groups.

So the main plastic we are expirementing is something similar to cellophane? Just Curious. Also could we make a device for extruding sheets of this, or only thin strands? Also what solvent is planned? I have seen Schweizer's Reagent used. Anyways, seems cool and good luck!
